1.0 GENERAL DESCRIPTION

The DDX-2160, DDX-2120 and DDX-2100 power devices are monolithic, dual channel H-Bridges that can provide audio power up to:

•

80 watts per channel @10%THD, 6

Ω

(DDX-2160)

•


Ω

(DDX-2160,

DDX-2120)

•


Ω

(DDX-2100) at very high efficiency.

Each device contains a logic interface, integrated bridge drivers, high efficiency MOSFET output transistors and protection circuitry. Each device may be used in DDX® Mode as a dual bridge or reconfigured as a single bridge with double the output current capability. Alternatively, in Binary

Mode, it may be configured as either a dual bridge or (at lower power output) a quad half-bridge or a combination of both types.

The benefits of the DDX® amplification system are: an all-digital design that eliminates the need for a digital to analog converter (DAC), and the high efficiency operation derived from the use of

Apogee's patented damped ternary pulse width modulation (PWM). This approach provides an efficiency advantage over conventional PWM designs of more than three times the efficiency of typical Class A/B amplifiers with music input signals.

3.0 DDX-2160, DDX-2120 and DDX-2100 POWER DEVICES

The DDX-2160, DDX-2120 and DDX-2100 Power Devices are dual channel H-Bridges that can deliver more than 80/75/65 watts per channel (<10%THD) of audio output power at very high efficiency. They convert both DDX

®

and binary-controlled PWM signals into audio power at the load. Each includes a logic interface, integrated bridge drivers, high efficiency MOSFET outputs, and thermal and short circuit protection circuitry. In DDX

®

mode, two logic level signals per channel are used to control high-speed

MOSFET switches to connect the speaker load to the input supply or to ground in a bridge configuration, according to Apogee's patented damped ternary PWM. In Binary Mode operation, both

Full Bridge and Half Bridge Modes are supported. These devices include over-current and thermal protection as well as under-voltage lockout with automatic recovery. A thermal warning status is also provided.

3.1 Logic Interface and Decode

The DDX-2160, DDX-2120 and DDX-2100 power outputs are controlled using one or two logic level timing signals. In order to provide a proper logic interface, the V

L

input must operate at the same voltage as the DDX

®

controller logic supply. VL (Logic Reference Voltage) is recommended to be powered and stable prior to Vcc achieving > 7V to assure proper power up sequence. VL is recommended to remain powered and stable until after Vcc has decayed below 7V during power removal.

The DDX-2160, DDX-2120 and DDX-2100 include protection circuitry for over-current and thermal overload conditions. A thermal warning pin TWARN is activated low (open-drain MOSFET) when the

IC temperature exceeds 130°C, in advance of the thermal shutdown protection. When a fault condition is detected (logical OR of over-current and thermal), an internal fault signal acts to immediately disable the output power MOSFETs, placing both H-bridges in a high impedance state. At the same time an open-drain MOSFET connected to the FAULT pin is switched on.

There are two possible modes subsequent to activating a fault. The first is a SHUTDOWN mode. With

FAULT (pull-up resistor) and TRI-STATE pins independent, an activated fault will disable the device, signaling low at the FAULT output. The device may subsequently be reset to normal operation by toggling the TRI-STATE pin from High to Low to High using an external logic signal.

The second is an AUTOMATIC recovery mode. This is depicted in the application circuit in Figure 17.

The FAULT and TRI-STATE pins are shorted together and connected to a time constant circuit comprising R

T

and C

T

. An activated FAULT will force a reset on the TRI-STATE pin causing normal





DDX-2160/DDX-2120/DDX-2100

operation to resume following a delay determined by the time constant of the circuit. If the fault condition is still presented, the circuit operation will continue repeating until such time as the fault condition is removed. An increase in the time constant of the circuit will produce a longer recovery interval. Care must be taken in the overall system design so as not to exceed the protection thresholds under normal operation.

The DDX-2160, DDX-2120 and DDX-2100 power and output pins are duplicated to provide a low impedance path for the device’s bridged outputs. All duplicate power, ground and output pins must be connected for proper operation. The PWRDN or TRI-STATE pins should be used to set all MOSFETS to the Hi-Z state during power-up until the logic power supply, V

L

, is settled.

3.4 Parallel Output/High Current Operation

When using DDX

®

Mode output, the DDX-2160, DDX-2120 and DDX-2100 outputs can be connected in parallel to increase the output current to a load. In this configuration the devices can provide over

160W@3

Ω

/ 150W@4

Ω

/ 130W@4

Ω

(see Figure 6). This mode is enabled with the CONFIG pin connected to VREG1 and the inputs combined INLA = INLB, INRA = INRB and outputs combined

OUTLA = OUTLB, OUTRA = OUTRB.

A passive two-pole low-pass filter is used on the DDX-2160, DDX-2120 and DDX-2100 power outputs to reconstruct an analog signal. System performance can be significantly affected by the output filter design and choice of components. (See appnote: AN-15, Component Selection for DDX Amplifiers .) A filter design for 6

Ω

/8

Ω

loads is shown in the Typical Application Circuit in Figure 17. Figure 19 shows a filter design for 4

Ω

loads. Figure 23 shows a filter for ½ bridge mode, 4

Ω

loads.

3.7 Power Dissipation &

Heat Sink Requirements

The power dissipated within the device will depend primarily on the supply voltage, load impedance, and output modulation level.

The surface mount package of the DDX-2160, DDX-2120 and

DDX-2100 include an exposed thermal slug on the top of the device to provide a direct thermal path from the integrated circuit to the heatsink. Careful consideration must be given to the overall thermal design. See Figure 4 for power derating.

Figure 5 shows the full-scale output power (0dB FS digital input with unity amplifier gain) as a function of Power Supply Voltage for 4, 6, and 8 Ohm loads in either DDX

®

Mode or Binary Full Bridge Mode.

Output power is constrained for higher impedance loads by the maximum voltage limit of the

DDX-2160, DDX-2120 and DDX-2100 ICs and by the over-current protection limit for lower impedance loads. The minimum threshold for the over-current protection circuit is 4.5/4.0/3.5A (at 25 ºC) but the typical threshold is 6A. Solid curves depict typical output power capability of each device. Dotted and dashed curves depict the output power capability constrained to the minimum current specification of for the DDX-2100, DDX-2120 and DDX-2160 respectively. The output power curves assume proper thermal management of the power device’s internal dissipation. See Figure 4.

NOTE: Output power at 10% THD is approximately 30% higher.

(NOTE: Curves taken at f = 1 kHz and using a 330uF blocking capacitor.)

Figure 7 depicts the output power as a function of power supply voltages for loads of 4, 6, and 8 Ohms when the DDX-2160, DDX-2120 and DDX-2100 are operated in a half-bridge Binary Mode. Solid curves depict typical performance and dotted and dashed curves depict the minimum current limit for the DDX-2100, DDX-2120 and DDX-2160 respectively. Once again, the output power curves assume proper thermal management of the power device’s internal dissipation.
