DESCRIPTION
The TLV320AIC3106 is a low-power stereo audio
codec with stereo headphone amplifier, as well as
multiple inputs and outputs programmable in
single-ended or fully differential configurations.
Extensive register-based power control is included,
enabling stereo 48-kHz DAC playback as low as 15
mW from a 3.3-V analog supply, making it ideal for
portable battery-powered audio and telephony
applications.
The record path of the TLV320AIC3106 contains
integrated microphone bias, digitally controlled stereo
microphone preamplifier, and automatic gain control
(AGC), with mix/mux capability among the multiple
analog inputs. Programmable filters are available
during record which can remove audible noise that
can occur during optical zooming in digital cameras.
The playback path includes mix/mux capability from
the stereo DAC and selected inputs, through
programmable volume controls, to the various
outputs.
The TLV320AIC3106 contains four high-power output
drivers as well as three fully differential output drivers.
The high-power output drivers are capable of driving
a variety of load configurations, including up to four
channels of single-ended 16-Ω headphones using
ac-coupling capacitors, or stereo 16-Ω headphones in
a capacitorless output configuration.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION (CONTINUED)
The stereo audio DAC supports sampling rates from 8 kHz to 96 kHz and includes programmable digital filtering
in the DAC path for 3D, bass, treble, midrange effects, speaker equalization, and de-emphasis for 32-kHz,
44.1-kHz, and 48-kHz rates. The stereo audio ADC supports sampling rates from 8 kHz to 96 kHz and is
preceded by programmable gain amplifiers or AGC that can provide up to 59.5-dB analog gain for low-level
microphone inputs. The TLV320AIC3106 provides an extremely high range of programmability for both attack (8
ms–1,408 ms) and for decay (0.05 s–22.4 s). This extended AGC range allows the AGC to be tuned for many
types of applications.
For battery saving applications where neither analog nor digital signal processing are required, the device can be
put in a special analog signal passthru mode. This mode significantly reduces power consumption, as most of the
device is powered down during this pass through operation.
The serial control bus supports SPI or I2C protocols, while the serial audio data bus is programmable for I2S,
left/right-justified, DSP, or TDM modes. A highly programmable PLL is included for flexible clock generation and
support for all standard audio rates from a wide range of available MCLKs, varying from 512 kHz to 50 MHz, with
special attention paid to the most popular cases of 12-MHz, 13-MHz, 16-MHz, 19.2-MHz, and 19.68-MHz system
clocks.
The TLV320AIC3106 operates from an analog supply of 2.7 V–3.6 V, a digital core supply of 1.65 V–1.95 V, and
a digital I/O supply of 1.1 V–3.6 V. The device is available in the 5-mm × 5-mm, 80-ball MicroStar Junior™ BGA
package and a 7-mm × 7-mm, 48-lead QFN package.

RθJP is the internal thermal resistance from junction to the thermal pad. It is required to limit the power dissipation within the device to
500 mW in all cases, including temperatures below 25°C. The TLV320AIC3106IRGZ must be soldered down to the copper (ground
plane) under the device to meet the thermal requirements.
ΨJT is defined by the following formula: ΨJT = [T (Junction) – T (Center of top of the case)]/(Total power)

Ratio of output level with 1-kHz full-scale sine-wave input, to the output level with the inputs short circuited, measured A-weighted over a
20-Hz to 20-kHz bandwidth using an audio analyzer.
All performance measurements done with 20-kHz low-pass filter and, where noted, A-weighted filter. Failure to use such a filter may
result in higher THD+N and lower SNR and dynamic range readings than shown in the Electrical Characteristics. The low-pass filter
removes out-of-band noise, which, although not audible, may affect dynamic specification values.

OVERVIEW
The TLV320AIC3106 is a highly flexible, low power, stereo audio codec with extensive feature integration,
intended for applications in smartphones, PDAs, and portable computing, communication, and entertainment
applications. Available in a 5x5mm 80-ball BGA (with 51 balls actually used) and 7x7mm 48-lead QFN, the
product integrates a host of features to reduce cost, board space, and power consumption in space-constrained,
battery-powered, portable applications.
The TLV320AIC3106 consists of the following blocks:
• Stereo audio multi-bit delta-sigma DAC (8 kHz–96 kHz)
• Stereo audio multi-bit delta-sigma ADC (8 kHz–96 kHz)
• Programmable digital audio effects processing (3-D, bass, treble, mid-range, EQ, notch filter, de-emphasis)
• Six audio inputs
• Four high-power audio output drivers (headphone drive capability)
• Three fully differential line output drivers
• Fully programmable PLL
• Headphone/headset jack detection with interrupt
Communication to the TLV320AIC3106 for control is pin-selectable (using the SELECT pin) as either SPI or I2C.
The SPI interface requires that the Slave Select signal (MFP0) be driven low to communicate with the
TLV320AIC3106. Data is then shifted into or out of the TLV320AIC3106 under control of the host
microprocessor, which also provides the serial data clock. The I2C interface supports both standard and fast
communication modes, and also enables cascading of up to four multiple codecs on the same I2C bus through
the use of two pins for addressing (MFP0, MFP1).
HARDWARE RESET
The TLV320AIC3106 requires a hardware reset after power-up for proper operation. After all power supplies are
at their specified values, the RESET pin must be driven low for at least 10 ns. If this reset sequence is not
performed, the TLV320AIC3106 may not respond properly to register reads/writes.
DIGITAL CONTROL SERIAL INTERFACE
The TLV320AIC3106 control interface supports SPI or I2C communication protocols, with the protocol selectable
using the SELECT pin. For SPI, SELECT should be tied high; for I2C, SELECT should be tied low. It is not
recommended to change the state of SELECT during device operation.

Figure 15. SPI Read
In the SPI control mode, the TLV320AIC3106 uses the pins MFP0=SSB, MFP1=SCLK, MFP2=MISO,
MFP3=MOSI as a standard SPI port with clock polarity setting of 0 (typical microprocessor SPI control bit CPOL
= 0). The SPI port allows full-duplex, synchronous, serial communication between a host processor (the master)
and peripheral devices (slaves). The SPI master (in this case, the host processor) generates the synchronizing
clock (driven onto SCLK) and initiates transmissions. The SPI slave devices (such as the TLV320AIC3106)
depend on a master to start and synchronize transmissions.
A transmission begins when initiated by an SPI master. The byte from the SPI master begins shifting in on the
slave MOSI pin under the control of the master serial clock (driven onto SCLK). As the byte shifts in on the MOSI
pin, a byte shifts out on the MISO pin to the master shift register.
The TLV320AIC3106 interface is designed so that with a clock phase bit setting of 1 (typical microprocessor SPI
control bit CPHA = 1), the master begins driving its MOSI pin and the slave begins driving its MISO pin on the
first serial clock edge. The SSB pin can remain low between transmissions; however, the TLV320AIC3106 only
interprets the first 8 bits transmitted after the falling edge of SSB as a command byte, and the next 8 bits as a
data byte only if writing to a register. Reserved register bits should be written to their default values.
SPI COMMUNICATION PROTOCOL
The TLV320AIC3106 is entirely controlled by registers. Reading and writing these registers is accomplished by
the use of an 8-bit command, which is sent to the MOSI pin of the part prior to the data for that register. The
command is constructed as shown in Table X. The first 7 bits specify the register address which is being written
or read, from 0 to 127 (decimal). The command word ends with an R/W bit, which specifies the direction of data
flow on the serial bus. In the case of a register write, the R/W bit should be set to 0. A second byte of data is
sent to the MOSI pin and contains the data to be written to the register.
Reading of registers is accomplished in similar fashion. The 8-bit command word sends the 7-bit register
address, followed by R/W bit = 1 to signify a register read is occurring,. The 8-bit register data is then clocked out
of the part on the MISO pin during the second 8 SCLK clocks in the frame.

The register map of the TLV320AIC3106 actually consists of multiple pages of registers, with each page
containing 128 registers. The register at address zero on each page is used as a page-control register, and
writing to this register determines the active page for the device. All subsequent read/write operations will access
the page that is active at the time, unless a register write is performed to change the active page. Only two
pages of registers are implemented in this product, with the active page defaulting to page 0 upon device reset.
For example, at device reset, the active page defaults to page 0, and thus all register read/write operations for
addresses 1 to 127 will access registers in page 0. If registers on page 1 must be accessed, the user must write
the 8-bit sequence 0x01 to register 0, the page control register, to change the active page from page 0 to page 1.

After this write, it is recommended the user also read back the page control register, to safely ensure the change
in page control has occurred properly. Future read/write operations to addresses 1 to 127 will now access
registers in page 1. When page 0 registers must be accessed again, the user writes the 8-bit sequence 0x00 to
register 0, the page control register, to change the active page back to page 0. After a recommended read of the
page control register, all further read/write operations to addresses 1 to 127 will now access page 0 registers
again.
Limitation on Register Writing
When writing registers in SPI mode related to the audio output drivers mux, mix, gain configuration, etc., do not
use the auto-increment mode. In addition, between two successive writes to these registers, the host should
keep MFP0 (SPI chip select) high for at least 6.25us, to ensure that the register writes have occurred properly.
CONTINUOUS READ / WRITE OPERATION
The TLV320AIC3106 includes the ability to read/write registers continuously, without needing to provide an
address for every register accessed. In SPI mode, a continuous write is executed by transitioning MFP0 (SPI
chip select) low to start the frame, sending the first 8-bit command word to read/write a particular register, and
then sending multiple bytes of register data, intended for the addressed register and those following. A
continuous read is done similarly, with multiple bytes read in from the addressed register and the following
registers on the page. When the MFP0 (SPI chip select) pin is transitioned high again, the frame ends, as does
the continuous read/write operation. A new frame must begin again with a new command word, to start the next
bus transaction.
Note that this continuous read/write operation does not continue past a page boundary. The user should not
attempt to read/write past the end of a page, since this may result in undesirable operation.
I2C CONTROL MODE
The TLV320AIC3106 supports the I2C control protocol when the SELECT pin is tied low, using 7-bit addressing
and capable of both standard and fast modes. For I2C fast mode, note that the minimum timing for each of
tHD-STA, tSU-STA, and tSU-STO is 0.9 us, as seen in Figure 16. When in I2C control mode, the
TLV320AIC3106 can be configured for one of four different addresses, using the multifunction pins MFP0 and
MFP1, which control the two LSBs of the device address. The 5 MSBs of the device address are fixed as 00110
and cannot be changed, while the two LSBs are given by MFP1:MFP0. This results in four possible device
addresses:

Figure 16. I C Interface Timing
I2C is a two-wire, open-drain interface supporting multiple devices and masters on a single bus. Devices on the
I2C bus only drive the bus lines LOW by connecting them to ground; they never drive the bus lines HIGH.
Instead, the bus wires are pulled HIGH by pull-up resistors, so the bus wires are HIGH when no device is driving
them LOW. This way, two devices cannot conflict; if two devices drive the bus simultaneously, there is no driver
contention.
Communication on the I2C bus always takes place between two devices, one acting as the master and the other
acting as the slave. Both masters and slaves can read and write, but slaves can only do so under the direction of
the master. Some I2C devices can act as masters or slaves, but the TLV320AIC3106 can only act as a slave
device.
An I2C bus consists of two lines, SDA and SCL. SDA carries data; SCL provides the clock. All data is transmitted
across the I2C bus in groups of eight bits. To send a bit on the I2C bus, the SDA line is driven to the appropriate
level while SCL is LOW (a LOW on SDA indicates the bit is zero; a HIGH indicates the bit is one). Once the SDA
line has settled, the SCL line is brought HIGH, then LOW. This pulse on SCL clocks the SDA bit into the
receivers shift register.
The I2C bus is bidirectional: the SDA line is used both for transmitting and receiving data. When a master reads
from a slave, the slave drives the data line; when a master sends to a slave, the master drives the data line.
Under normal circumstances the master drives the clock line.
Most of the time the bus is idle, no communication is taking place, and both lines are HIGH. When
communication is taking place, the bus is active. Only master devices can start a communication. They do this by
causing a START condition on the bus. Normally, the data line is only allowed to change state while the clock
line is LOW. If the data line changes state while the clock line is HIGH, it is either a START condition or its
counterpart, a STOP condition. A START condition is when the clock line is HIGH and the data line goes from
HIGH to LOW. A STOP condition is when the clock line is HIGH and the data line goes from LOW to HIGH.
After the master issues a START condition, it sends a byte that indicates which slave device it wants to
communicate with. This byte is called the address byte. Each device on an I2C bus has a unique 7-bit address to
which it responds. (Slaves can also have 10-bit addresses; see the I2C specification for details.) The master
sends an address in the address byte, together with a bit that indicates whether it wishes to read from or write to
the slave device.
Every byte transmitted on the I2C bus, whether it is address or data, is acknowledged with an acknowledge bit.
When a master has finished sending a byte (eight data bits) to a slave, it stops driving SDA and waits for the
slave to acknowledge the byte. The slave acknowledges the byte by pulling SDA LOW. The master then sends a
clock pulse to clock the acknowledge bit. Similarly, when a master has finished reading a byte, it pulls SDA LOW
to acknowledge this to the slave. It then sends a clock pulse to clock the bit.

A not-acknowledge is performed by simply leaving SDA HIGH during an acknowledge cycle. If a device is not
present on the bus, and the master attempts to address it, it will receive a not−acknowledge because no device
is present at that address to pull the line LOW.
When a master has finished communicating with a slave, it may issue a STOP condition. When a STOP
condition is issued, the bus becomes idle again. A master may also issue another START condition. When a
START condition is issued while the bus is active, it is called a repeated START condition.
The TLV320AIC3106 also responds to and acknowledges a General Call, which consists of the master issuing a
command with a slave address byte of 00H.

Figure 18. I2C Read
In the case of an I2C register write, if the master does not issue a STOP condition, then the device enters
auto-increment mode. So in the next eight clocks, the data on SDA is treated as data for the next incremental
register.
Similarly, in the case of an I2C register read, after the device has sent out the 8-bit data from the addressed
register, if the master issues an ACKNOWLEDGE, the slave takes over control of SDA bus and transmit for the
next 8 clocks the data of the next incremental register.
I2C BUS DEBUG IN A GLITCHED SYSTEM
Occasionally, some systems may encounter noise or glitches on the I2C bus. In the unlikely event that this
affects bus performance, then it can be useful to use the I2C Debug register. This feature terminates the I2C bus
error allowing this I2C device and system to resume communications. The I2C bus error detector is enabled by
default. The TLV320AIC3106 I2C error detector status can be read from Page 0, Register 107, bit D0. If desired,
the detector can be disabled by writing to Page 0, Register 107, bit D2.
DIGITAL AUDIO DATA SERIAL INTERFACE
Audio data is transferred between the host processor and the TLV320AIC3106 via the digital audio data serial
interface, or audio bus. The audio bus on this device is very flexible, including left or right justified data options,
support for I2S or PCM protocols, programmable data length options, a TDM mode for multichannel operation,
very flexible master/slave configurability for each bus clock line, and the ability to communicate with multiple
devices within a system directly.
The data serial interface uses two sets of pins for communication between external devices, with the particular
pin used controlled through register programming. This configuration is shown in Figure 19 below.

Figure 19. Alternate Audio Bus Mulitplexing Function
In cases where MFP3 is needed for a secondary device digital input, the TLV320AIC3106 must be used in I2C
mode (when in SPI mode, MFP3 is used as the SPI bus MOSI pin and thus cannot be used here as an alternate
digital input source).
This mux capability allows the TLV320AIC3106 to communicate with two separate devices with independent
I2S/PCM buses. An example of such an application is a cellphone containing a Bluetooth transceiver with
PCM/I2S interface, as shown in Figure 20. The applications processor can be connected to the WCLK, BCLK,
DIN, DOUT pins on the TLV320AIC3106, while a Bluetooth device with PCM interface can be connected to the
GPIO1, GPIO2, MFP3, and DOUT pins on the TLV320AIC3106. By programming the registers via I2C control,
the applications processor can determine which device is communicating with the TLV320AIC3106. This is
attractive in cases where the TLV320AIC3106 can be configured to communicate data with the Bluetooth device,
then the applications processor can be put into a low power sleep mode, while voice/audio transmission still
occurs between the Bluetooth device and the TLV320AIC3106.

These modes are all MSB-first, with data width programmable as 16, 20, 24, or 32 bits. In addition, the word
clock (WCLK or GPIO1) and bit clock (BCLK or GPIO2) can be independently configured in either Master or

The word clock (WCLK or GPIO1) is used to define the beginning of a frame, and may be programmed as either
a pulse or a square-wave signal. The frequency of this clock corresponds to the maximum of the selected ADC
and DAC sampling frequencies.
The bit clock (BCLK or GPIO2) is used to clock in and out the digital audio data across the serial bus. When in
Master mode, this signal can be programmed in two further modes: continuous transfer mode, and 256-clock
mode. In continuous transfer mode, only the minimal number of bit clocks needed to transfer the audio data are
generated, so in general the number of bit clocks per frame will be two times the data width. For example, if data
width is chosen as 16 bits, then 32 bit clocks will be generated per frame. If the bit clock signal in master mode
will be used by a PLL in another device, it is recommended that the 16-bit or 32-bit data width selections be
used. These cases result in a low jitter bit clock signal being generated, having frequencies of 32 × fS or 64 × fS.
In the cases of 20-bit and 24-bt data width in master mode, the bit clocks generated in each frame will not all be
of equal period, due to the device not having a clean 40 × fS or 48 × fS clock signal readily available. The
average frequency of the bit clock signal is still accurate in these cases (being 40 × fS or 48 × fS), but the
resulting clock signal has higher jitter than in the 16-bit and 32-bit cases.
In 256-clock mode, a constant 256 bit clocks per frame are generated, independent of the data width chosen.
The TLV320AIC3106 further includes programmability to 3-state the DOUT line during all bit clocks when valid
data is not being sent. By combining this capability with the ability to program at what bit clock in a frame the
audio data will begin, time-division multiplexing (TDM) can be accomplished, resulting in multiple codecs able to
use a single audio serial data bus.
When the audio serial data bus is powered down while configured in master mode, the pins associated with the
interface will be put into a 3-state output condition.
RIGHT-JUSTIFIED MODE
In right-justified mode, the LSB of the left channel is valid on the rising edge of the bit clock preceding the falling
edge of word clock. Similarly, the LSB of the right channel is valid on the rising edge of the bit clock preceding
the rising edge of the word clock.

TDM DATA TRANSFER
Time-division multiplexed data transfer can be realized in any of the above transfer modes if the 256-clock bit
clock mode is selected, although it is recommended to be used in either left-justified mode or DSP mode. By
changing the programmable offset, the bit clock in each frame where the data begins can be changed, and the
serial data output driver (DOUT) can also be programmed to 3-state during all bit clocks except when valid data
is being put onto the bus. This allows other codecs to be programmed with different offsets and to drive their
data onto the same DOUT line, just in a different slot. For incoming data, the codec simply ignores data on the
bus except where it is expected based on the programmed offset.
Note that the location of the data when an offset is programmed is different, depending on what transfer mode is
selected. In DSP mode, both left and right channels of data are transferred immediately adjacent to each other in
the frame. This differs from left-justified mode, where the left and right channel data will always be a half-frame
apart in each frame. In this case, as the offset is programmed from zero to some higher value, both the left and
right channel data move across the frame, but still stay a full half-frame apart from each other. This is depicted in
Figure 25 for the two cases.

AUDIO DATA CONVERTERS
The TLV320AIC3106 supports the following standard audio sampling rates: 8 kHz, 11.025 kHz, 12 kHz, 16 kHz,
22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz. The converters can also operate at
different sampling rates in various combinations, which are described further below.
The data converters are based on the concept of an fS(ref) rate that is used internal to the part, and it is related to
the actual sampling rates of the converters through a series of ratios. For typical sampling rates, fS(ref) will be
either 44.1 kHz or 48 kHz, although it can realistically be set over a wider range of rates up to 53 kHz, with
additional restrictions applying if the PLL is used. This concept is used to set the sampling rates of the ADC and
DAC, and also to enable high quality playback of low sampling rate data, without high frequency audible noise
being generated.
The sampling rate of the ADC and DAC can be set to fS(ref)/NDAC or 2×fS(ref)/NDAC, with NDAC being 1, 1.5, 2,
2.5, 3, 3.5, 4, 4.5, 5, 5.5, or 6.
While only one fS(ref) can be used at a time in the part, the ADC and DAC sampling rates can differ from each
other by using different NADC and NDAC divider ratios for each. For example, with fS(ref)=44.1-kHz, the DAC
sampling rate can be set to 44.1-kHz by using NDAC=1, while the ADC sampling rate can be set to 8.018-kHz by
using NADC=5.5.
When the ADCs and DACs are operating at different sampling rates, an additional word clock is required, to
provide information regarding where data begins for the ADC versus the DAC. In this case, the standard bit clock
signal (which can be supplied through the BCLK pin or through GPIO2) is used to transfer both ADC and DAC
data, the standard word clock signal is used to identify the start of the DAC data, and a separate ADC word clock
signal (denoted ADWK) is used. This clock can be supplied or generated from GPIO1 at the same time the DAC
word clock is supplied or generated from WCLK.
AUDIO CLOCK GENERATION
The audio converters in the TLV320AIC3106 need an internal audio master clock at a frequency of 256 × fS(ref),
which can be obtained in a variety of manners from an external clock signal applied to the device.
A more detailed diagram of the audio clock section of the TLV320AIC3106 is shown in Figure 26.

The part can accept an MCLK input from 512 kHz to 50 MHz, which can then be passed through either a
programmable divider or a PLL, to get the proper internal audio master clock needed by the part. The BCLK or
GPIO2 inputs can also be used to generate the internal audio master clock.
This design also allows the PLL to be used for an entirely separate purpose in a system, if the audio codec is not
powered up. The user can supply a separate clock to GPIO2, route this through the PLL, with the resulting output
clock driven out GPIO1, for use by other devices in the system
A primary concern is proper operation of the codec at various sample rates with the limited MCLK frequencies
available in the system. This device includes a highly programmable PLL to accommodate such situations easily.
The integrated PLL can generate audio clocks from a wide variety of possible MCLK inputs, with particular focus
paid to the standard MCLK rates already widely used.

The TLV320AIC3106 can also output a separate clock on the GPIO1 pin. If the PLL is being used for the audio
data converter clock, the M and N settings can be used to provide a divided version of the PLL output. If the PLL
is not being used for the audio data converter clock, the PLL can still be enabled to provide a completely
independent clock output on GPIO1. The formula for the GPIO1 clock output when PLL is enabled and
CLKMUX_OUT is 0 is:
GPIO1 = (PLLCLK_IN× 2 × K × R) / (M × N × P)
When CLKMUX_OUT is 1, regardless of whether PLL is enabled or disabled, the input to the clock output divider
can be selected as MCLK, BCLK, or GPIO2. Is this case, the formula for the GPIO1 clock is:
GPIO1 = (CLKDIV_IN × 2) / (M × N), where
M = 1, 2, 4, 8
N = 2, 3, …, 17
CLKDIV_IN can be BCLK, MCLK, or GPIO2, selected by page 0, register 102, bits D7-D6
STEREO AUDIO ADC
The TLV320AIC3106 includes a stereo audio ADC, which uses a delta-sigma modulator with 128-times
oversampling in single-rate mode, followed by a digital decimation filter. The ADC supports sampling rates from 8
kHz to 48 kHz in single-rate mode, and up to 96 kHz in dual-rate mode. Whenever the ADC or DAC is in
operation, the device requires that an audio master clock be provided and appropriate audio clock generation be
set up within the device.
In order to provide optimal system power dissipation, the stereo ADC can be powered one channel at a time, to
support the case where only mono record capability is required. In addition, both channels can be fully powered
or entirely powered down.
The integrated digital decimation filter removes high-frequency content and downsamples the audio data from an
initial sampling rate of 128 fS to the final output sampling rate of fS. The decimation filter provides a linear phase
output response with a group delay of 17/fS. The –3-dB bandwidth of the decimation filter extends to 0.45 fS and
scales with the sample rate (fS). The filter has minimum 75-dB attenuation over the stop band from 0.55 fS to 64
fS. Independent digital high-pass filters are also included with each ADC channel, with a corner frequency that
can be independently set.
Because of the oversampling nature of the audio ADC and the integrated digital decimation filtering,
requirements for analog antialiasing filtering are very relaxed. The TLV320AIC3106 integrates a second-order
analog antialiasing filter with 20-dB attenuation at 1 MHz. This filter, combined with the digital decimation filter,
provides sufficient antialiasing filtering without requiring additional external components.
The ADC is preceded by a programmable gain amplifier (PGA), which allows analog gain control from 0 dB to
59.5 dB in steps of 0.5 dB. The PGA gain changes are implemented with an internal soft-stepping algorithm that
only changes the actual volume level by one 0.5-dB step every one or two ADC output samples, depending on
the register programming (see page 0, registers 19 and 22). This soft-stepping ensures that volume control
changes occur smoothly with no audible artifacts. On reset, the PGA gain defaults to a mute condition, and on
power down, the PGA soft-steps the volume to mute before shutting down. A read-only flag is set whenever the
gain applied by PGA equals the desired value set by the register. The soft-stepping control can also be disabled
by programming a register bit. When soft stepping is enabled, the audio master clock must be applied to the part
after the ADC power-down register is written to ensure the soft-stepping to mute has completed. When the ADC
power-down flag is no longer set, the audio master clock can be shut down.

STEREO AUDIO ADC HIGH-PASS FILTER
Often in audio applications it is desirable to remove the dc offset from the converted audio data stream. The
TLV320AIC3106 has a programmable first-order high-pass filter which can be used for this purpose. The digital
filter coefficients are in 16-bit format and therefore use two 8-bit registers for each of the three coefficients, N0,
N1, and D1. The transfer function of the digital high-pass filter is of the form:
*1
H(z) + N0 ) N1 z *1
32, 768 * D1 z
(1)
Programming the left channel is done by writing to page 1, registers 65–70, and the right channel is programmed
by writing to page 1, registers 71–76. After the coefficients have been loaded, these ADC high-pass filter
coefficients can be selected by writing to page 0, register 107, bits D7–D6, and the high-pass filter can be
enabled by writing to page 0, register 12, bits D7–D4.
DIGITAL AUDIO PROCESSING FOR RECORD PATH

In applications where record only is selected, and DAC is powered down, the playback path signal processing
blocks can be used in the ADC record path. These filtering blocks can support high pass, low pass, band pass or
notch filtering. In this mode, the record only path has switches SW-D1 through SW-D4 closed, and reroutes the
ADC output data through the digital signal processing blocks. Since the DAC's Digital Signal Processing blocks
are being re-used, naturally the addresses of these digital filter coefficients are the same as for the DAC digital
processing and are located on Page 1, Registers 1-52. This record only mode is enabled by powering down both
DACs by writing to Page 0, Register 37, bits D7-D6 (D7=D6=”0”). Next, enable the digital filter pathway for the
ADC by writing a “1” to Page 0, Register 107, bit D3. (Note, this pathway is only enabled if both DACs are
powered down.) This record only path can be seen in Figure 27.

AUTOMATIC GAIN CONTROL (AGC)
An automatic gain control (AGC) circuit is included with the ADC and can be used to maintain nominally constant
output signal amplitude when recording speech signals (it can be fully disabled if not desired). This circuitry
automatically adjusts the PGA gain as the input signal becomes overly loud or very weak, such as when a
person speaking into a microphone moves closer or farther from the microphone. The AGC algorithm has several
programmable settings, including target gain, attack and decay time constants, noise threshold, and maximum
PGA gain applicable that allow the algorithm to be fine tuned for any particular application. The algorithm uses
the absolute average of the signal (which is the average of the absolute value of the signal) as a measure of the
nominal amplitude of the output signal.
Note that completely independent AGC circuitry is included with each ADC channel with entirely independent
control over the algorithm from one channel to the next. This is attractive in cases where two microphones are
used in a system, but may have different placement in the end equipment and require different dynamic
performance for optimal system operation.
Target level represents the nominal output level at which the AGC attempts to hold the ADC output signal level.
The TLV320AIC3106 allows programming of eight different target levels, which can be programmed from –5.5
dB to –24 dB relative to a full-scale signal. Since the device reacts to the signal absolute average and not to
peak levels, it is recommended that the target level be set with enough margin to avoid clipping at the occurrence
of loud sounds.
Attack time determines how quickly the AGC circuitry reduces the PGA gain when the input signal is too loud. It
can be varied from 7 ms to 1,408 ms. The extended Right Channel Attack time can be programmed by writing to
Page 0, Registers 103, and Left Channel is programmed by writing to Page 0, Register 105.
Decay time determines how quickly the PGA gain is increased when the input signal is too low. It can be varied
in the range from 0.05 s to 22.4 s. The extended Right Channel Decay time can be programmed by writing to
Page 0, Registers 104, and Left Channel is programmed by writing to Page 0, Register 106.
The actual AGC decay time maximum is based on a counter length, so the maximum decay time will scale with
the clock set up that is used. The table below shows the relationship of the NADC ratio to the maximum time
available for the AGC decay. In practice, these maximum times are extremely long for audio applications and
should not limit any practical AGC decay time that is needed by the system.

Noise gate threshold determines the level below which if the input speech average value falls, AGC considers it
as a silence and hence brings down the gain to 0 dB in steps of 0.5 dB every FS and sets the noise threshold
flag. The gain stays at 0 dB unless the input speech signal average rises above the noise threshold setting. This
ensures that noise does not get gained up in the absence of speech. Noise threshold level in the AGC algorithm
is programmable from –30 dB to –90 dB relative to full scale. A disable noise gate feature is also available. This
operation includes programmable debounce and hysteresis functionality to avoid the AGC gain from cycling
between high gain and 0 dB when signals are near the noise threshold level. When the noise threshold flag is
set, the status of gain applied by the AGC and the saturation flag should be ignored.

Maximum PGA gain applicable allows the user to restrict the maximum PGA gain that can be applied by the
AGC algorithm. This can be used for limiting PGA gain in situations where environmental noise is greater than
programmed noise threshold. It can be programmed from 0 dB to 59.5 dB in steps of 0.5 dB.

Note that the time constants here are correct when the ADC is not in double-rate audio mode. The time
constants are achieved using the fS(ref) value programmed in the control registers. However, if the fS(ref) is set in
the registers to, for example, 48 kHz, but the actual audio clock or PLL programming actually results in a different
fS(ref) in practice, then the time constants would not be correct.
The actual AGC decay time maximum is based on a counter length, so the maximum decay time scales with the
clock set up that is used. Table 1 shows the relationship of the NADC ratio to the maximum time available for the
AGC decay. In practice, these maximum times are extremely long for audio applications and should not limit any
practical AGC decay time that is needed by the system.
STEREO AUDIO DAC
The TLV320AIC3106 includes a stereo audio DAC supporting sampling rates from 8 kHz to 96 kHz. Each
channel of the stereo audio DAC consists of a digital audio processing block, a digital interpolation filter, multi-bit
digital delta-sigma modulator, and an analog reconstruction filter. The DAC is designed to provide enhanced
performance at low sampling rates through increased oversampling and image filtering, thereby keeping
quantization noise generated within the delta-sigma modulator and signal images strongly suppressed within the
audio band to beyond 20 kHz. This is realized by keeping the upsampled rate constant at 128 × fS(ref) and
changing the oversampling ratio as the input sample rate is changed. For an fS(ref) of 48 kHz, the digital
delta-sigma modulator always operates at a rate of 6.144 MHz. This ensures that quantization noise generated
within the delta-sigma modulator stays low within the frequency band below 20 kHz at all sample rates. Similarly,
for an fS(ref) rate of 44.1 kHz, the digital delta-sigma modulator always operates at a rate of 5.6448 MHz.
The following restrictions apply in the case when the PLL is powered down and double-rate audio mode is
enabled in the DAC.

DIGITAL AUDIO PROCESSING FOR PLAYBACK
The DAC channel consists of optional filters for de-emphasis and bass, treble, midrange level adjustment,
speaker equalization, and 3-D effects processing. The de-emphasis function is implemented by a programmable
digital filter block with fully programmable coefficients (see Page-1/Reg-21-26 for left channel, Page-1/Reg-47-52
for right channel). If de-emphasis is not required in a particular application, this programmable filter block can be
used for some other purpose. The de-emphasis filter transfer function is given by:
*1
H(z) + N0 ) N1 z *1
32768 * D1 z
(2)
where the N0, N1, and D1 coefficients are fully programmable individually for each channel. The coefficients that
should be loaded to implement standard de-emphasis filters are given in Table 2.

In addition to the de-emphasis filter block, the DAC digital effects processing includes a fourth order digital IIR

sections with frequency response given by:

The coefficients for this filter implement a variety of sound effects, with bass-boost or treble boost being the most
commonly used in portable audio applications. The default N and D coefficients in the part are given in Table 3
and implement a shelving filter with 0-dB gain from DC to approximately 150 Hz, at which point it rolls off to a
3-dB attenuation for higher frequency signals, thus giving a 3-dB boost to signals below 150 Hz. The N and D
coefficients are represented by 16-bit two’s complement numbers with values ranging from –32768 to 32767.

The digital processing also includes capability to implement 3-D processing algorithms by providing means to
process the mono mix of the stereo input, and then combine this with the individual channel signals for stereo
output playback. The architecture of this processing mode, and the programmable filters available for use in the
system, is shown in Figure 30. Note that the programmable attenuation block provides a method of adjusting the
level of 3-D effect introduced into the final stereo output. This combined with the fully programmable biquad filters
in the system enables the user to fully optimize the audio effects for a particular system and provide extensive
differentiation from other systems using the same device.

It is recommended that the digital effects filters should be disabled while the filter coefficients are being modified.
While new coefficients are being written to the device over the control port, it is possible that a filter using
partially updated coefficients may actually implement an unstable system and lead to oscillation or objectionable
audio output. By disabling the filters, changing the coefficients, and then re-enabling the filters, these types of
effects can be entirely avoided.
DIGITAL INTERPOLATION FILTER
The digital interpolation filter upsamples the output of the digital audio processing block by the required
oversampling ratio before data is provided to the digital delta-sigma modulator and analog reconstruction filter
stages. The filter provides a linear phase output with a group delay of 21/fS. In addition, programmable digital
interpolation filtering is included to provide enhanced image filtering and reduce signal images caused by the
upsampling process that are below 20 kHz. For example, upsampling an 8-kHz signal produces signal images at
multiples of 8-kHz (i.e., 8 kHz, 16 kHz, 24 kHz, etc.). The images at 8 kHz and 16 kHz are below 20 kHz and still
audible to the listener; therefore, they must be filtered heavily to maintain a good quality output. The interpolation

filter is designed to maintain at least 65-dB rejection of images that land below 7.455 fS. In order to utilize the
programmable interpolation capability, the fS(ref) should be programmed to a higher rate (restricted to be in the
range of 39 kHz to 53 kHz when the PLL is in use), and the actual fS is set using the NDAC divider. For example,
if fS = 8 kHz is required, then fS(ref) can be set to 48 kHz, and the DAC fS set to fS(ref)/6. This ensures that all
images of the 8-kHz data are sufficiently attenuated well beyond a 20-kHz audible frequency range.
DELTA-SIGMA AUDIO DAC
The stereo audio DAC incorporates a third order multi-bit delta-sigma modulator followed by an analog
reconstruction filter. The DAC provides high-resolution, low-noise performance, using oversampling and noise
shaping techniques. The analog reconstruction filter design consists of a 6-tap analog FIR filter followed by a
continuous time RC filter. The analog FIR operates at a rate of 128 × fS(ref) (6.144 MHz when fS(ref) = 48 kHz,
5.6448 MHz when fS(ref) = 44.1 kHz). Note that the DAC analog performance may be degraded by excessive
clock jitter on the MCLK input. Therefore, care must be taken to keep jitter on this clock to a minimum.
AUDIO DAC DIGITAL VOLUME CONTROL
The audio DAC includes a digital volume control block which implements a programmable digital gain. The
volume level can be varied from 0 dB to –63.5 dB in 0.5-dB steps, in addition to a mute bit, independently for
each channel. The volume level of both channels can also be changed simultaneously by the master volume
control. Gain changes are implemented with a soft-stepping algorithm, which only changes the actual volume by
one step per input sample, either up or down, until the desired volume is reached. The rate of soft-stepping can
be slowed to one step per two input samples through a register bit.
Because of soft-stepping, the host does not know when the DAC has been actually muted. This may be
important if the host wishes to mute the DAC before making a significant change, such as changing sample
rates. In order to help with this situation, the device provides a flag back to the host via a read-only register bit
that alerts the host when the part has completed the soft-stepping and the actual volume has reached the
desired volume level. The soft-stepping feature can be disabled through register programming. If soft-stepping is
enabled, the MCLK signal should be kept applied to the device until the DAC power-down flag is set. When this
flag is set, the internal soft-stepping process and power down sequence is complete, and the MCLK can then be
stopped if desired.
The TLV320AIC3106 also includes functionality to detect when the user switches on or off the de-emphasis or
digital audio processing functions, to first (1) soft-mute the DAC volume control, (2) change the operation of the
digital effects processing, and (3) soft-unmute the part. This avoids any possible pop/clicks in the audio output
due to instantaneous changes in the filtering. A similar algorithm is used when first powering up or down the
DAC. The circuit begins operation at power up with the volume control muted, then soft-steps it up to the desired
volume level. At power down, the logic first soft-steps the volume down to a mute level, then powers down the
circuitry.
INCREASING DAC DYNAMIC RANGE
The TLV320AIC3106 allows trading off dynamic range with power consumption. The DAC dynamic range can be
increased by writing to Page 0, Register 109 bits D7-D6. The lowest DAC current setting is the default, and the
dynamic range is displayed in the datasheet table. Increasing the current can increase the DAC dynamic range
by up to 1.5dB.
ANALOG OUTPUT COMMON-MODE ADJUSTMENT
The output common-mode voltage and output range of the analog output are determined by an internal bandgap
reference, in contrast to other codecs that may use a divided version of the supply. This scheme is used to
reduce the coupling of noise that may be on the supply (such as 217-Hz noise in a GSM cellphone) into the
audio signal path.
However, due to the possible wide variation in analog supply range (2.7 V – 3.6 V), an output common-mode
voltage setting of 1.35 V, which would be used for a 2.7 V supply case, will be overly conservative if the supply is
actually much larger, such as 3.3 V or 3.6 V. In order to optimize device operation, the TLV320AIC3106 includes

appropriate to the actual supply range used by a particular customer. The output common-mode level can be
varied among four different values, ranging from 1.35 V (most appropriate for low supply ranges, near 2.7 V) to
1.8 V (most appropriate for high supply ranges, near 3.6 V). Note that there is also some limitation on the range

AUDIO DAC POWER CONTROL
The stereo DAC can be fully powered up or down, and in addition, the analog circuitry in each DAC channel can
be powered up or down independently. This provides power savings when only a mono playback stream is
needed.
AUDIO ANALOG INPUTS
The TLV320AIC3106 includes ten analog audio input pins, which can be configured as up to four fully-differential
pair plus one single-ended pair of audio inputs, or up to six single-ended audio inputs. . These pins connect
through series resistors and switches to the virtual ground terminals of two fully differential opamps (one per
ADC/PGA channel). By selecting to turn on only one set of switches per opamp at a time, the inputs can be
effectively muxed to each ADC PGA channel.
By selecting to turn on multiple sets of switches per opamp at a time, mixing can also be achieved. Mixing of
multiple inputs can easily lead to PGA outputs that exceed the range of the internal opamps, resulting in
saturation and clipping of the mixed output signal. Whenever mixing is being implemented, the user should take
adequate precautions to avoid such a saturation case from occurring. In general, the mixed signal should not
exceed 2 Vpp (single-ended) or 4 Vpp (differential).
In most mixing applications, there is also a general need to adjust the levels of the individual signals being
mixed. For example, if a soft signal and a large signal are to be mixed and played together, the soft signal
generally should be amplified to a level comparable to the large signal before mixing. In order to accommodate
this need, the TLV320AIC3106 includes input level control on each of the individual inputs before they are mixed
or muxed into the ADC PGAs, with gain programmable from 0 dB to –12 dB in 1.5 dB steps. Note that this input
level control is not intended to be a volume control, but instead used occasionally for level setting. Soft-stepping
of the input level control settings is implemented in this device, with the speed and functionality following the
settings used by the ADC PGA for soft-stepping.
The TLV320AIC3106 supports the ability to mix up to three fully-differential analog inputs into each ADC PGA
channel. Figure 31 shows the mixing configuration for the left channel, which can mix the signals

Inputs can also be selected as single-ended instead of fully-differential, and mixing or muxing into the ADC PGAs
is also possible in this mode. It is not possible, however, for an input pair to be selected as fully-differential for
connection to one ADC PGA and simultaneously selected as single-ended for connection to the other ADC PGA
channel. However, it is possible for an input to be selected or mixed into both left and right channel PGAs, as
long as it has the same configuration for both channels (either both single-ended or both fully-differential).
Figure 32 shows the single-ended mixing configuration for the left channel ADC PGA, which enables mixing of
the signals LINE1LP, LINE2LP, LINE1RP, MIC3L, and MIC3R. The right channel ADC PGA mix is similar,
enabling mixing of the signals LINE1RP, LINE2RP, LINE1LP, MIC3L, and MIC3R.

ANALOG INPUT BYPASS PATH FUNCTIONALITY
The TLV320AIC3106 includes the additional ability to route some analog input signals past the integrated data
converters, for mixing with other analog signals and then direct connection to the output drivers. This capability is
useful in a cellphone, for example, when a separate FM radio device provides a stereo analog output signal that
needs to be routed to headphones. The TLV320AIC3106 supports this in a low power mode by providing a direct
analog path through the device to the output drivers, while all ADCs and DACs can be completely powered down
to save power.
For fully-differential inputs, the TLV320AIC3106 provides the ability to pass the signals LINE2LP-LINE2LM and
LINE2RP-LINE2RM to the output stage directly. If in single-ended configuration, the device can pass the signal
LINE2LP and LINE2RP to the output stage directly.

ADC PGA SIGNAL BYPASS PATH FUNCTIONALITY
In addition to the input bypass path described above, the TLV320AIC3106 also includes the ability to route the
ADC PGA output signals past the ADC, for mixing with other analog signals and then direct connection to the
output drivers. These bypass functions are described in more detail in the sections on output mixing and output
driver configurations.
INPUT IMPEDANCE AND VCM CONTROL
The TLV320AIC3106 includes several programmable settings to control analog input pins, particularly when they
are not selected for connection to an ADC PGA. The default option allows unselected inputs to be put into a
3-state condition, such that the input impedance seen looking into the device is extremely high. Note, however,
that the pins on the device do include protection diode circuits connected to AVDD and AVSS. Thus, if any
voltage is driven onto a pin approximately one diode drop (~0.6 V) above AVDD or one diode drop below AVSS,
these protection diodes will begin conducting current, resulting in an effective impedance that no longer appears
as a 3-state condition.
Another programmable option for unselected analog inputs is to weakly hold them at the common-mode input
voltage of the ADC PGA (which is determined by an internal bandgap voltage reference). This is useful to keep
the ac-coupling capacitors connected to analog inputs biased up at a normal DC level, thus avoiding the need for
them to charge up suddenly when the input is changed from being unselected to selected for connection to an
ADC PGA. This option is controlled in Page-0/Reg-20 and 23. The user should ensure this option is disabled
when an input is selected for connection to an ADC PGA or selected for the analog input bypass path, since it
can corrupt the recorded input signal if left operational when an input is selected.
In most cases, the analog input pins on the TLV320AIC3106 should be ac-coupled to analog input sources, the
only exception to this generally being if an ADC is being used for DC voltage measurement. The ac-coupling
capacitor will cause a highpass filter pole to be inserted into the analog signal path, so the size of the capacitor
must be chosen to move that filter pole sufficiently low in frequency to cause minimal effect on the processed
analog signal. The input impedance of the analog inputs when selected for connection to an ADC PGA varies
with the setting of the input level control, starting at approximately 20 kΩ with an input level control setting of
0-dB, and increasing to approximately 80-kΩ when the input level control is set at –12 dB. For example, using a
0.1 µF ac-coupling capacitor at an analog input will result in a highpass filter pole of 80 Hz when the 0 dB input
level control setting is selected.
PASSIVE ANALOG BYPASS DURING POWERDOWN
Programming the TLV320AIC3106 to Passive Analog bypass occurs by configuring the output stage switches for
pass through. This is done by opening switches SW-L0, SW-L3, SW-R0, SW-R3 and closing either SW-L1 or
SW-L2 and SW-R1 or SW-R2. See Figure 33 Passive Analog Bypass Mode Configuration. Programming this
mode is done by writing to Page 0, Register 108.
Connecting MIC1LP/LINE1LP input signal to the LEFT_LOP pin is done by closing SW-L1 and opening SW-L0,
this action is done by writing a “1” to Page 0, Register 108, Bit D0. Connecting MIC2LP/LINE2LP input signal to
the LEFT_LOP pin is done by closing SW-L2 and opening SW-L0, this action is done by writing a “1” to Page 0,
Register 108, Bit D2. Connecting MIC1LM/LINE1LM input signal to the LEFT_LOM pin is done by closing SW-L4
and opening SW-L3, this action is done by writing a “1” to Page 0, Register 108, Bit D1. Connecting
MIC2LM/LINE2LM input signal to the LEFT_LOM pin is done by closing SW-L5 and opening SW-L3, this action
is done by writing a “1” to Page 0, Register 108, Bit D3.
Connecting MIC1RP/LINE1RP input signal to the RIGHT_LOP pin is done by closing SW-R1 and opening
SW-R0, this action is done by writing a “1” to Page 0, Register 108, Bit D4. Connecting MIC2RP/LINE2RP input
signal to the RIGHT_LOP pin is done by closing SW-R2 and opening SW-R0, this action is done by writing a “1”
to Page 0, Register 108, Bit D6. Connecting MIC1RM/LINE1RM input signal to the RIGHT_LOM pin is done by
closing SW-R4 and opening SW-R3, this action is done by writing a “1” to Page 0, Register 108, Bit D5.
Connecting MIC2RM/LINE2RM input signal to the RIGHT_LOM pin is done by closing SW-R5 and opening
SW-R3, this action is done by writing a “1” to Page 0, Register 108, Bit D7. A diagram of the passive analog
bypass mode configuration can be seen in Figure 33.
In general, connecting two switches to the same output pin should be avoided, as this error will short two input
signals together, and would like cause distortion of the signal as the two signal are in contention, and poor
frequency response would also likely occur.

MICBIAS GENERATION
The TLV320AIC3106 includes a programmable microphone bias output voltage (MICBIAS), capable of providing
output voltages of 2.0 V or 2.5 V (both derived from the on-chip bandgap voltage) with 4-mA output current drive.
In addition, the MICBIAS may be programmed to be switched to AVDD directly through an on-chip switch, or it
can be powered down completely when not needed, for power savings. This function is controlled by register
programming in Page-0/Reg-25.
DIGITAL MICROPHONE CONNECTIVITY
The TLV320AIC3106 includes support for connection of a digital microphone to the device by routing the digital
signal directly into the ADC digital decimation filter, where it is filtered, downsampled, and provided to the host
processor over the audio data serial bus.
When digital microphone mode is enabled, the TLV320AIC3106 provides an oversampling clock output for use
by the digital microphone to transmit its data. The TLV320AIC3106 includes the capability to latch the data on
either the rising, falling, or both edges of this supplied clock, enabling support for stereo digital microphones.
In this mode, the oversampling ratio of the digital mic modulator can be programmed as 128, 64 or 32 times the
ADC sample rate, ADCFS. The GPIO1 pin will output the serial oversampling clock at the programmed rate.
TLV320AIC3106 latches the data input on GPIO2 as the Left and Right channel digital microphone data. For the
Left channel input, GPIO2 will be sampled on the rising edge of the clock, and for the Right channel input,
GPIO2 will be sampled on the falling edge of the clock. If a single digital mic channel is needed then the
corresponding ADC channel should be powered up, and the unused channel should be powered down. When
digital microphone mode is enabled, neither ADC can be used for digitizing analog inputs.
Configuring the digital microphone configuration set up is done by writing to Page 0, Register 107, bits D5-D4,
and Register 25, bits D5-D4.

ANALOG FULLY DIFFERENTIAL LINE OUTPUT DRIVERS
The TLV320AIC3106 has two fully differential line output drivers, each capable of driving a 10-kΩ differential
load. The output stage design leading to the fully differential line output drivers is shown in Figure 34 and
Figure 35. This design includes extensive capability to adjust signal levels independently before any mixing
occurs, beyond that already provided by the PGA gain and the DAC digital volume control.
The LINE2L/R signals refer to the signals that travel through the analog input bypass path to the output stage.
The PGA_L/R signals refer to the outputs of the ADC PGA stages that are similarly passed around the ADC to
the output stage. Note that since both left and right channel signals are routed to all output drivers, a mono mix
of any of the stereo signals can easily be obtained by setting the volume controls of both left and right channel
signals to –6 dB and mixing them. Undesired signals can also be disconnected from the mix as well through
register control.

Figure 35. Detail of the Volume Control and Mixing Function Shown in Figure 29 and Figure 17
The DAC_L/R signals are the outputs of the stereo audio DAC, which can be steered by register control based
on the requirements of the system. If mixing of the DAC audio with other signals is not required, and the DAC
output is only needed at the stereo line outputs, then it is recommended to use the routing through path
DAC_L3/R3 to the fully differential stereo line outputs. This results not only in higher quality output performance,
but also in lower power operation, since the analog volume controls and mixing blocks ahead of these drivers
can be powered down.
If instead the DAC analog output must be routed to multiple output drivers simultaneously (such as to
LEFT_LOP/M, RIGHT_LOP/M, and MONO_LOP/M) or must be mixed with other analog signals, then the DAC
outputs should be switched through the DAC_L1/R1 path. This option provides the maximum flexibility for routing
of the DAC analog signals to the output drivers
The TLV320AIC3106 includes an output level control on each output driver with limited gain adjustment from 0
dB to 9 dB. The output driver circuitry in this device are designed to provide a low distortion output while playing
fullscale stereo DAC signals at a 0dB gain setting. However, a higher amplitude output can be obtained at the
cost of increased signal distortion at the output. This output level control allows the user to make this tradeoff
based on the requirements of the end equipment. Note that this output level control is not intended to be used as
a standard output volume control. It is expected to be used only sparingly for level setting, i.e., adjustment of the
fullscale output range of the device.
Each differential line output driver can be powered down independently of the others when it is not needed in the
system. When placed into powerdown through register programming, the driver output pins will be placed into a
3-stated, high-impedance state.
ANALOG HIGH POWER OUTPUT DRIVERS
The TLV320AIC3106 includes four high power output drivers with extensive flexibility in their usage. These
output drivers are individually capable of driving 30 mW each into a 16-Ω load in single-ended configuration, and
they can be used in pairs connected in bridge-terminated load (BTL) configuration between two driver outputs.
The high power output drivers can be configured in a variety of ways, including:
1. driving up to two fully differential output signals
2. driving up to four single-ended output signals
3. driving two single-ended output signals, with one or two of the remaining drivers driving a fixed VCM level,
for a pseudo-differential stereo output

The output stage architecture leading to the high power output drivers is shown in Figure 36, with the volume
control and mixing blocks being effectively identical to that shown in Figure 35. Note that each of these drivers
have a output level control block like those included with the line output drivers, allowing gain adjustment up to
+9dB on the output signal. As in the previous case, this output level adjustment is not intended to be used as a
standard volume control, but instead is included for additional fullscale output signal level control.
Two of the output drivers, HPROUT and HPLOUT, include a direct connection path for the stereo DAC outputs to
be passed directly to the output drivers and bypass the analog volume controls and mixing networks, using the
DAC_L2/R2 path. As in the line output case, this functionality provides the highest quality DAC playback
performance with reduced power dissipation, but can only be utilized if the DAC output does not need to route to
multiple output drivers simultaneously, and if mixing of the DAC output with other analog signals is not needed.

Figure 36. Architecture of the Output Stage Leading to the High Power Output Drivers
The high power output drivers include additional circuitry to avoid artifacts on the audio output during power-on
and power-off transient conditions. The user should first program the type of output configuration being used in
Page-0/Reg-14, to allow the device to select the optimal power-up scheme to avoid output artifacts. The
power-up delay time for the high power output drivers is also programmable over a wide range of time delays,
from instantaneous up to 4-sec, using Page-0/Reg-42.

TLV320AIC3106
SLAS509E – DECEMBER 2006 – REVISED DECEMBER 2008........................................................................................................................................ www.ti.com
When these output drivers are powered down, they can be placed into a variety of output conditions based on
register programming. If lowest power operation is desired, then the outputs can be placed into a 3-state
condition, and all power to the output stage is removed. However, this generally results in the output nodes
drifting to rest near the upper or lower analog supply, due to small leakage currents at the pins. This then results
in a longer delay requirement to avoid output artifacts during driver power-on. In order to reduce this required
power-on delay, the TLV320AIC3106 includes an option for the output pins of the drivers to be weakly driven to
the VCM level they would normally rest at when powered with no signal applied. This output VCM level is
determined by an internal bandgap voltage reference, and thus results in extra power dissipation when the
drivers are in powerdown. However, this option provides the fastest method for transitioning the drivers from
powerdown to full power operation without any output artifact introduced.
The device includes a further option that falls between the other two – while it requires less power drawn while
the output drivers are in powerdown, it also takes a slightly longer delay to power-up without artifact than if the
bandgap reference is kept alive. In this alternate mode, the powered-down output driver pin is weakly driven to a
voltage of approximately half the DRVDD1/2 supply level using an internal voltage divider. This voltage will not
match the actual VCM of a fully powered driver, but due to the output voltage being close to its final value, a
much shorter power-up delay time setting can be used and still avoid any audible output artifacts. These output
voltage options are controlled in Page-0/Reg-42.
The high power output drivers can also be programmed to power up first with the output level control in a highly
attenuated state, then the output driver will automatically slowly reduce the output attenuation to reach the
desired output level setting programmed. This capability is enabled by default but can be enabled in
Page-0/Reg-40.
SHORT CIRCUIT OUTPUT PROTECTION
The TLV320AIC3106 includes programmable short-circuit protection for the high power output drivers, for
maximum flexibility in a given application. By default, if these output drivers are shorted, they will automatically
limit the maximum amount of current that can be sourced to or sunk from a load, thereby protecting the device
from an over-current condition. In this mode, the user can read Page-0/Reg-95 to determine whether the part is
in short-circuit protection or not, and then decide whether to program the device to power down the output
drivers. However, the device includes further capability to automatically power down an output driver whenever it
does into short-circuit protection, without requiring intervention from the user. In this case, the output driver will
stay in a power down condition until the user specifically programs it to power down and then power back up
again, to clear the short-circuit flag.
JACK/HEADSET DETECTION
The TLV320AIC3106 includes extensive capability to monitor a headphone, microphone, or headset jack,
determine if a plug has been inserted into the jack, and then determine what type of headset/headphone is wired
to the plug. Figure 37 shows one configuration of the device that enables detection and determination of headset
type when a pseudo-differential (capless) stereo headphone output configuration is used. The registers used for
this function are page 0, registers 14, 96, 97, and 13. The type of headset detected can be read back from page
0, register 13. Note that for best results, it is recommended to select a MICBIAS value as high as possible, and
to program the output driver common-mode level at a 1.35-V or 1.5-V level.

GENERAL-PURPOSE I/O
TLV320AIC3106 has two dedicated pins for general-purpose I/O. These pins can be used to read status of
external signals through register read when configured as general-purpose input. When configured as
general-purpose output , these pins can also drive logic high or low. Besides these standard GPIO functions,
these pins can also be used in a variety of ways, such as output for internal clocks and interrupt signals. The
TLV320AIC3106 generates a variety of interrupts of use to the host processor such interrupts on jack detection,
button press, short-circuit detection, and AGC noise detection. All these interrupts can be routed individually to
the GPIO pins or can be combined by a logical OR. In case of a combined interrupt, the user can read an
internal status register to find the actual cause of interrupt. When configured as interrupt, the TLV320AIC3106
also offers the flexibility of generating a single pulse or a train of pulses until the interrupt status register is read
by the user.
CONTROL REGISTERS
The control registers for the TLV320AIC3106 are described in detail below. All registers are 8 bit in width, with
D7 referring to the most significant bit of each register, and D0 referring to the least significant bit.

stage network, connected to each of the analog signals that route to the output stage. In addition, to enable
completely independent mixing operations to be performed for each output driver, each analog signal coming into
the output stage may have up to seven separate volume controls. These volume controls all have approximately
0.5-dB step programmability over most of the gain range, with steps increasing slightly at the lowest attenuations.
Table 5 lists the detailed gain versus programmed setting for this basic volume control.

Based on the setting above, if BOTH LINE1 and LINE2 inputs are routed to the output at the same time, then the two switches used for
the connection short the two input signals together on the output pins. The shorting resistance between the two input pins is two times
the bypass switch resistance (Rdson). In general this condition of shorting should be avoided, as higher drive currents are likely to occur
on the circuitry that feeds these two input pins of this device.
