DESCRIPTION
The TAS5713 is a 25-W, efficient, digital-audio power
amplifier for driving stereo bridge-tied speakers. One
serial data input allows processing of up to two
discrete audio channels and seamless integration to
most digital audio processors and MPEG decoders.
The device accepts a wide range of input data and
data rates. A fully programmable data path routes
these channels to the internal speaker drivers.
The TAS5713 is a slave-only device receiving all
clocks from external sources. The TAS5713 operates
with a PWM carrier between a 384-kHz switching rate
and a 352-KHz switching rate, depending on the input
sample rate. Oversampling combined with a
fourth-order noise shaper provides a flat noise floor
and excellent dynamic range from 20 Hz to 20 kHz..

This pin is monitored on the rising edge of RESET. A value of 0
(15-kΩ pulldown) sets the I2C device address to 0x34 and a value of
1 (15-kΩ pullup) sets it to 0x36. this dual-function pin can be
programmed to output internal power-stage errors.
TYPE: A = analog; D = 3.3-V digital; P = power/ground/decoupling; I = input; O = output
All pullups are weak pullups and all pulldowns are weak pulldowns. The pullups and pulldowns are included to assure proper input logic
levels if the pins are left unconnected (pullups → logic 1 input; pulldowns → logic 0 input).

DETAILED DESCRIPTION
POWER SUPPLY
To facilitate system design, the TAS5713 needs only a 3.3-V supply in addition to the (typical) 18-V power-stage
supply. An internal voltage regulator provides suitable voltage levels for the gate drive circuitry. Additionally, all
circuitry requiring a floating voltage supply, e.g., the high-side gate drive, is accommodated by built-in bootstrap
circuitry requiring only a few external capacitors.
In order to provide good electrical and acoustical characteristics, the PWM signal path for the output stage is
designed as identical, independent half-bridges. For this reason, each half-bridge has separate bootstrap pins
(BST_x), and power-stage supply pins (PVDD_x). The gate-drive voltage (GVDD_OUT) is derived from the
PVDD voltage. Special attention should be paid to placing all decoupling capacitors as close to their associated
pins as possible. Inductance between the power-supply pins and decoupling capacitors must be avoided.
For a properly functioning bootstrap circuit, a small ceramic capacitor must be connected from each bootstrap pin
(BST_x) to the power-stage output pin (OUT_x). When the power-stage output is low, the bootstrap capacitor is
charged through an internal diode connected between the gate-drive regulator output pin (GVDD_OUT) and the
bootstrap pin. When the power-stage output is high, the bootstrap capacitor potential is shifted above the output
potential and thus provides a suitable voltage supply for the high-side gate driver. In an application with PWM
switching frequencies in the range from 352 kHz to 384 kHz, it is recommended to use 33-nF, X7R ceramic
capacitors, size 0603 or 0805, for the bootstrap supply. These 33-nF capacitors ensure sufficient energy storage,
even during minimal PWM duty cycles, to keep the high-side power-stage FET (LDMOS) fully turned on during
the remaining part of the PWM cycle.
Special attention should be paid to the power-stage power supply; this includes component selection, PCB
placement, and routing. As indicated, each half-bridge has independent power-stage supply pins (PVDD_x). For
optimal electrical performance, EMI compliance, and system reliability, it is important that each PVDD_x pin is
decoupled with a 100-nF, X7R ceramic capacitor placed as close as possible to each supply pin.
The TAS5713 is fully protected against erroneous power-stage turnon due to parasitic gate charging.
I2C CHIP SELECT
A_SEL_FAULT is an input pin during power up. It can be pulled high (15-kΩ pullup) or low (15-kΩ pulldown).
High indicates an I2C subaddress of 0x36, and low a subaddress of 0x34.
I2C Device Address Change Procedure
•
Write to device address change enable register, 0xF8 with a value of 0xF9 A5 A5 A5.
•
Write to device register 0xF9 with a value of 0x0000 00XX, where XX is the new address.
•
Any writes after that should use the new device address XX.
SINGLE-FILTER PBTL MODE
The TAS5713 supports parallel BTL (PBTL) mode with OUT_A/OUT_B (and OUT_C/OUT_D) connected before
the LC filter. In order to put the part in PBTL configuration, drive PBTL (pin 8) HIGH. This synchronizes the
turnoff of half-bridges A and B (and similarly C/D) if an overcurrent condition is detected in either half-bridge.
There is a pulldown resistor on the PBTL pin that configures the part in BTL mode if the pin is left floating.
PWM output multiplexers should be updated to set the device in PBTL mode. Output Mux Register (0x25) should
be written with a value of 0x01 10 32 45. Also, the PWM shutdown register (0x19) should be written with a value
of 0x3A.
DEVICE PROTECTION SYSTEM
Overcurrent (OC) Protection With Current Limiting
The device has independent, fast-reacting current detectors on all high-side and low-side power-stage FETs. The
detector outputs are closely monitored by two protection systems. The first protection system controls the power
stage in order to prevent the output current further increasing, i.e., it performs a cycle-by-cycle current-limiting
function, rather than prematurely shutting down during combinations of high-level music transients and extreme

speaker load-impedance drops. If the high-current condition situation persists, i.e., the power stage is being
overloaded, a second protection system triggers a latching shutdown, resulting in the power stage being set in
the high-impedance (Hi-Z) state. The device returns to normal operation once the fault condition (i.e., a short
circuit on the output) is removed. Current-limiting and overcurrent protection are not independent for half-bridges.
That is, if the bridge-tied load between half-bridges A and B causes an overcurrent fault, half-bridges A, B, C,
and D are shut down.
Overtemperature Protection
The TAS5713 has an overtemperature-protection system. If the device junction temperature exceeds 150°C
(nominal), the device is put into thermal shutdown, resulting in all half-bridge outputs being set in the
high-impedance (Hi-Z) state and A_SEL_FAULT being asserted low. The TAS5713 recovers automatically once
the temperature drops approximately 30°C.
Undervoltage Protection (UVP) and Power-On Reset (POR)
The UVP and POR circuits of the TAS5713 fully protect the device in any power-up/down and brownout situation.
While powering up, the POR circuit resets the overload circuit (OLP) and ensures that all circuits are fully
operational when the PVDD and AVDD supply voltages reach 7.6 V and 2.7 V, respectively. Although PVDD and
AVDD are independently monitored, a supply-voltage drop below the UVP threshold on AVDD or either PVDD
pin results in all half-bridge outputs immediately being set in the high-impedance (Hi-Z) state and A_SEL_FAULT
being asserted low.
FAULT INDICATION
A_SEL_FAULT is an input pin during power up. This pin can be programmed after RESET to be an output by
writing 1 to bit 0 of I2C register 0x05. In that mode, the(A_SEL_FAULT pin has the definition shown in Table 1.
Any fault resulting in device shutdown is signaled by the A_SEL_FAULT pin going low (see Table 1). A latched
version of this pin is available on D1 of register 0x02. This bit can be reset only by an I2C write.

SSTIMER FUNCTIONALITY
The SSTIMER pin uses a capacitor connected between this pin and ground to control the output duty cycle when
exiting all-channel shutdown. The capacitor on the SSTIMER pin is slowly charged through an internal current
source, and the charge time determines the rate at which the output transitions from a near-zero duty cycle to the
desired duty cycle. This allows for a smooth transition that minimizes audible pops and clicks. When the part is
shut down, the drivers are placed in the high-impedance state and transition slowly down through a 3-kΩ resistor,
similarly minimizing pops and clicks. The shutdown transition time is independent of the SSTIMER pin
capacitance. Larger capacitors increase the start-up time, while capacitors smaller than 2.2 nF decrease the
start-up time. The SSTIMER pin should be left floating for BD modulation.
CLOCK, AUTODETECTION, AND PLL
The TAS5713 is an I2S slave device. It accepts MCLK, SCLK, and LRCLK. The digital audio processor (DAP)
supports all the sample rates and MCLK rates that are defined in the clock control register .
The TAS5713 checks to verify that SCLK is a specific value of 32 fS, 48 fS, or 64 fS. The DAP only supports a 1 ×
fS LRCLK. The timing relationship of these clocks to SDIN is shown in subsequent sections. The clock section
uses MCLK or the internal oscillator clock (when MCLK is unstable, out of range, or absent) to produce the
internal clock (DCLK) running at 512 times the PWM switching frequency.
The DAP can autodetect and set the internal clock control logic to the appropriate settings for all supported clock
rates as defined in the clock-control register.

SLOS637A – DECEMBER 2009 – REVISED AUGUST 2010

The TAS5713 has robust clock error handling that uses the built-in trimmed oscillator clock to quickly detect
changes/errors. Once the system detects a clock change/error, it mutes the audio (through a single-step mute)
and then forces PLL to limp using the internal oscillator as a reference clock. Once the clocks are stable, the
system autodetects the new rate and revert to normal operation. During this process, the default volume is
restored in a single step (also called hard unmute). The ramp process can be programmed to ramp back slowly
(also called soft unmute) as defined in volume register (0x0E).
SERIAL DATA INTERFACE
Serial data is input on SDIN. The PWM outputs are derived from SDIN. The TAS5713 DAP accepts serial data in
16-, 20-, or 24-bit left-justified, right-justified, and I2S serial data formats.
PWM SECTION
The TAS5713 DAP device uses noise-shaping and customized nonlinear correction algorithms to achieve high
power efficiency and high-performance digital audio reproduction. The DAP uses a fourth-order noise shaper to
increase dynamic range and SNR in the audio band. The PWM section accepts 24-bit PCM data from the DAP
and outputs two BTL PWM audio output channels.
The PWM section has individual-channel dc-blocking filters that can be enabled and disabled. The filter cutoff
frequency is less than 1 Hz. Individual-channel de-emphasis filters for 44.1 kHz and 48 kHz are included and can
be enabled and disabled.
Finally, the PWM section has an adjustable maximum modulation limit of 93.8% to 99.2%.
For a detailed description of using audio processing features like DRC and EQ, see the User's Guide and
TAS570X GDE software development tool documentation.
SERIAL INTERFACE CONTROL AND TIMING
I2S Timing
I2S timing uses LRCLK to define when the data being transmitted is for the left channel and when it is for the
right channel. LRCLK is low for the left channel and high for the right channel. A bit clock running at 32, 48, or
64 × fS is used to clock in the data. There is a delay of one bit clock from the time the LRCLK signal changes
state to the first bit of data on the data lines. The data is written MSB-first and is valid on the rising edge of bit
clock. The DAP masks unused trailing data bit positions.

I2C SERIAL CONTROL INTERFACE
The TAS5713 DAP has a bidirectional I2C interface that is compatible with the Inter IC (I2C) bus protocol and
supports both 100-kHz and 400-kHz data transfer rates for single- and multiple-byte write and read operations.
This is a slave-only device that does not support a multimaster bus environment or wait-state insertion. The
control interface is used to program the registers of the device and to read device status.
The DAP supports the standard-mode I2C bus operation (100 kHz maximum) and the fast I2C bus operation
(400 kHz maximum). The DAP performs all I2C operations without I2C wait cycles.
General I2C Operation
The I2C bus employs two signals, SDA (data) and SCL (clock), to communicate between integrated circuits in a
system. Data is transferred on the bus serially, one bit at a time. The address and data can be transferred in byte
(8-bit) format, with the most-significant bit (MSB) transferred first. In addition, each byte transferred on the bus is
acknowledged by the receiving device with an acknowledge bit. Each transfer operation begins with the master
device driving a start condition on the bus and ends with the master device driving a stop condition on the bus.
The bus uses transitions on the data pin (SDA) while the clock is high to indicate start and stop conditions. A
high-to-low transition on SDA indicates a start and a low-to-high transition indicates a stop. Normal data-bit
transitions must occur within the low time of the clock period. These conditions are shown in Figure 41. The
master generates the 7-bit slave address and the read/write (R/W) bit to open communication with another
device and then waits for an acknowledge condition. The TAS5713 holds SDA low during the acknowledge clock
period to indicate an acknowledgment. When this occurs, the master transmits the next byte of the sequence.
Each device is addressed by a unique 7-bit slave address plus R/W bit (1 byte). All compatible devices share the
same signals via a bidirectional bus using a wired-AND connection. An external pullup resistor must be used for
the SDA and SCL signals to set the high level for the bus.

Figure 41. Typical I2C Sequence
There is no limit on the number of bytes that can be transmitted between start and stop conditions. When the last
word transfers, the master generates a stop condition to release the bus. A generic data transfer sequence is
shown in Figure 41.
The 7-bit address for the TAS5713 is 0011 011 (0x36) or 0011 010 (ox34) based on the polarity of the
A_SEL_FAULT pin.
The TAS5713 address can be changed from 0x36 to 0x38 by writing 0x38 to device address register 0xF9.
Single- and Multiple-Byte Transfers
The serial control interface supports both single-byte and multiple-byte read/write operations for subaddresses
0x00 to 0x1F. However, for the subaddresses 0x20 to 0xFF, the serial control interface supports only
multiple-byte read/write operations (in multiples of 4 bytes).
During multiple-byte read operations, the DAP responds with data, a byte at a time, starting at the subaddress
assigned, as long as the master device continues to respond with acknowledges. If a particular subaddress does
not contain 32 bits, the unused bits are read as logic 0.

SLOS637A – DECEMBER 2009 – REVISED AUGUST 2010
During multiple-byte write operations, the DAP compares the number of bytes transmitted to the number of bytes
that are required for each specific subaddress. For example, if a write command is received for a biquad
subaddress, the DAP must receive five 32-bit words. If fewer than five 32-bit data words have been received
when a stop command (or another start command) is received, the received data is discarded.
Supplying a subaddress for each subaddress transaction is referred to as random I2C addressing. The TAS5713
also supports sequential I2C addressing. For write transactions, if a subaddress is issued followed by data for
that subaddress and the 15 subaddresses that follow, a sequential I2C write transaction has taken place, and the
data for all 16 subaddresses is successfully received by the TAS5713. For I2C sequential-write transactions, the
subaddress then serves as the start address, and the amount of data subsequently transmitted, before a stop or
start is transmitted, determines how many subaddresses are written. As was true for random addressing,
sequential addressing requires that a complete set of data be transmitted. If only a partial set of data is written to
the last subaddress, the data for the last subaddress is discarded. However, all other data written is accepted;
only the incomplete data is discarded.
Single-Byte Write
As shown in Figure 42, a single-byte data-write transfer begins with the master device transmitting a start
condition followed by the I2C device address and the read/write bit. The read/write bit determines the direction of
the data transfer. For a data-write transfer, the read/write bit is a 0. After receiving the correct I2C device address
and the read/write bit, the DAP responds with an acknowledge bit. Next, the master transmits the address byte or
bytes corresponding to the TAS5713 internal memory address being accessed. After receiving the address byte,
the TAS5713 again responds with an acknowledge bit. Next, the master device transmits the data byte to be
written to the memory address being accessed. After receiving the data byte, the TAS5713 again responds with
an acknowledge bit. Finally, the master device transmits a stop condition to complete the single-byte data-write
transfer.

Single-Byte Read
As shown in Figure 44, a single-byte data-read transfer begins with the master device transmitting a start
condition, followed by the I2C device address and the read/write bit. For the data read transfer, both a write
followed by a read are actually done. Initially, a write is done to transfer the address byte or bytes of the internal
memory address to be read. As a result, the read/write bit becomes a 0. After receiving the TAS5713 address
and the read/write bit, TAS5713 responds with an acknowledge bit. In addition, after sending the internal memory
address byte or bytes, the master device transmits another start condition followed by the TAS5713 address and
the read/write bit again. This time, the read/write bit becomes a 1, indicating a read transfer. After receiving the
address and the read/write bit, the TAS5713 again responds with an acknowledge bit. Next, the TAS5713
transmits the data byte from the memory address being read. After receiving the data byte, the master device
transmits a not-acknowledge followed by a stop condition to complete the single-byte data-read transfer.

BANK SWITCHING
The TAS5713 uses an approach called bank switching together with automatic sample-rate detection. All
processing features that must be changed for different sample rates are stored internally in three banks. The
user can program which sample rates map to each bank. By default, bank 1 is used in the 32-kHz mode, bank 2
is used in the 44.1/48-kHz mode, and bank 3 is used for all other rates. Combined with the clock-rate
autodetection feature, bank switching allows the TAS5713 to detect automatically a change in the input sample
rate and switch to the appropriate bank without any MCU intervention.
An external controller configures bankable locations (0x29–0x36, 0x3A–0x3F, and 0x58–0x5F) for all three banks
during the initialization sequence.
If automatic bank switching is enabled (register 0x50, bits 2:0) , then the TAS5713 automatically swaps the
coefficients for subsequent sample-rate changes, avoiding the need for any external controller intervention for a
sample-rate change.
By default, bits 2:0 have the value 000; indicating that bank switching is disabled. In that state, updates to
bankable locations take immediate effect. A write to register 0x50 with bits 2:0 being 001, 010, or 011 brings the
system into the coefficient-bank-update state update bank1, update bank2, or update bank3, respectively. Any
subsequent write to bankable locations updates the coefficient banks stored outside the DAP. After updating all
the three banks, the system controller should issue a write to register 0x50 with bits 2:0 being 100; this changes
the system state to automatic bank switching mode. In automatic bank switching mode, the TAS5713
automatically swaps banks based on the sample rate.
Command sequences for updating DAP coefficients can be summarized as follows:
1. Bank switching disabled (default): DAP coefficient writes take immediate effect and are not
influenced by subsequent sample-rate changes.
OR
Bank switching enabled:
(a) Update bank-1 mode: Write 001 to bits 2:0 of register 0x50. Load the 32-kHz coefficients.
(b) Update bank-2 mode: Write 010 to bits 2:0 of register 0x50. Load the 48-kHz coefficients.
(c) Update bank-3 mode: Write 011 to bits 2:0 of register 0x50. Load the other coefficients.
(d) Enable automatic bank switching by writing 100 to bits 2:0 of reg 0x50.
26-Bit 3.23 Number Format
All mixer gain coefficients are 26-bit coefficients using a 3.23 number format. Numbers formatted as 3.23
numbers means that there are 3 bits to the left of the binary point and 23 bits to the right of the binary point. This
is shown in Figure 48 .

The decimal value of a 3.23 format number can be found by following the weighting shown in Figure 48. If the
most significant bit is logic 0, the number is a positive number, and the weighting shown yields the correct
number. If the most significant bit is a logic 1, then the number is a negative number. In this case every bit must
be inverted, a 1 added to the result, and then the weighting shown in Figure 49 applied to obtain the magnitude
of the negative number.

Initialization Sequence
Use the following sequence to power-up and initialize the device:
1.
Hold all digital inputs low and ramp up AVDD/DVDD to at least 3 V.
2.
Initialize digital inputs and PVDD supply as follows:
•
Drive RESET = 0, PDN = 1, and other digital inputs to their desired state while ensuring that
all are never more than 2.5 V above AVDD/DVDD. Wait at least 100 µs, drive RESET = 1,
and wait at least another 13.5 ms.
•
Ramp up PVDD to at least 8 V while ensuring that it remains below 6 V for at least 100 µs
after AVDD/DVDD reaches 3 V. Then wait at least another 10 µs.
3.
Trim oscillator (write 0x00 to register 0x1B) and wait at least 50 ms.
4.
Configure the DAP via I2C (see Users's Guide for typical values).
5.
Configure remaining registers.
6.
Exit shutdown (sequence defined below).
Normal Operation
The following are the only events supported during normal operation:
1.
Writes to master/channel volume registers.
2.
Writes to soft mute register.
3.
Enter and exit shutdown (sequence defined below).
Note: Event 3 is not supported for 240 ms + 1.3 × tstart after trim following AVDD/DVDD powerup ramp
(where tstart is specified by register 0x1A).

Shutdown Sequence
Enter:
1.
Write 0x40 to register 0x05.
2.
Wait at least 1 ms + 1.3 × tstop (where tstop is specified by register 0x1A).
3.
If desired, reconfigure by returning to step 4 of initialization sequence.
1.
Write 0x00 to register 0x05 (exit shutdown command may not be serviced for as much as 240 ms
after trim following AVDD/DVDD powerup ramp).
2.
Wait at least 1 ms + 1.3 × tstart (where tstart is specified by register 0x1A).
3.
Proceed with normal operation.
Exit:
Power-Down Sequence
Use the following sequence to powerdown the device and its supplies:
1.
If time permits, enter shutdown (sequence defined above); else, in case of sudden power loss,
assert PDN = 0 and wait at least 2 ms.
2.
Assert RESET = 0.
3.
Drive digital inputs low and ramp down PVDD supply as follows:
4.

•
Drive all digital inputs low after RESET has been low for at least 2 µs.
•
Ramp down PVDD while ensuring that it remains above 8 V until RESET has been low for at
least 2 µs.
Ramp down AVDD/DVDD while ensuring that it remains above 3 V until PVDD is below 6 V and
that it is never more than 2.5 V below the digital inputs.

ERROR STATUS REGISTER (0x02)
The error bits are sticky and are not cleared by the hardware. This means that the software must clear the
register (write zeroes) and then read them to determine if they are persistent errors.
Error definitions:
• MCLK Error : MCLK frequency is changing. The number of MCLKs per LRCLK is changing.
• SCLK Error: The number of SCLKs per LRCLK is changing.
• LRCLK Error: LRCLK frequency is changing.
• Frame slip: LRCLK phase is drifting with respect to internal frame sync.

SYSTEM CONTROL REGISTER 1 (0x03)
System control register 1 has several functions:
Bit D7:
If 0, the dc-blocking filter for each channel is disabled.
If 1, the dc-blocking filter (–3 dB cutoff <1 Hz) for each channel is enabled (default).
Bit D5:
If 0, use soft unmute on recovery from a clock error. This is a slow recovery. Unmute takes the
same time as the volume ramp defined in register 0x0E.
If 1, use hard unmute on recovery from clock error (default). This is a fast recovery, a single-step
volume ramp.
Bits D1–D0: Select de-emphasis

ICD settings have high impact on audio performance (e.g., dynamic range, THD, crosstalk, etc.) Therefore,
appropriate ICD settings must be used. By default, the device has ICD settings for the AD mode. If used in BD
mode, then update these registers before coming out of all-channel shutdown.

PWM SHUTDOWN GROUP REGISTER (0x19)
Settings of this register determine which PWM channels are active. The value should be 0x30 for BTL mode and
0x3A for PBTL mode. The default value of this register is 0x30. The functionality of this register is tied to the
state of bit D5 in the system control register.
This register defines which channels belong to the shutdown group (SDG). If a 1 is set in the shutdown group
register, that particular channel is not started following an exit out of all-channel shutdown command (if bit D5 is
set to 0 in system control register 2, 0x05).

START/STOP PERIOD REGISTER (0x1A)
This register is used to control the soft-start and soft-stop period following an enter/exit all-channel shutdown
command or change in the PDN state. This helps reduce pops and clicks at start-up and shutdown. The times
are only approximate and vary depending on device activity level and I2S clock stability.

OSCILLATOR TRIM REGISTER (0x1B)
The TAS5713 PWM processor contains an internal oscillator to support autodetect of I2S clock rates. This
reduces system cost because an external reference is not required. Currently, TI recommends a reference
resistor value of 18.2 kΩ (1%). This should be connected between OSC_RES and DVSSO.
Writing 0x00 to register 0x1B enables the trim that was programmed at the factory.
Note that trim must always be run following reset of the device.

BKND_ERR REGISTER (0x1C)
When a back-end error signal is received from the internal power stage, the power stage is reset stopping all
PWM activity. Subsequently, the modulator waits approximately for the time listed in Table 19 before attempting
to re-start the power stage.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

Multiple Top-Side Markings will be inside parentheses. Only one Top-Side Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a
continuation of the previous line and the two combined represent the entire Top-Side Marking for that device.

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s noncompliance with the terms and provisions of this Notice.
