† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Pulse duration = 10 ms, duty cycle2%

The TPA032D01 is a monolithic power IC stereo audio amplifier that operates in extremely efficient Class-D operation, using the high switching speed of power DMOS transistors to replicate the analog input signal through high-frequency switching of the output stage. This allows the TPA032D02 to be configured as a bridge-tied load (BTL) amplifier capable of delivering up to 10 W of continuous average power into a 4-W load at 0.5% THD+N from a 12-V power supply in the high-fidelity audio frequency range (20 Hz to 20 kHz). A BTL configuration eliminates the need for external coupling capacitors on the output. A chip-level shutdown control is provided to limit total supply current to 20 mA, making the device ideal for battery-powered applications.

The output stage of TPA032D01  is compatible with a range of power supplies from 8 V to 14 V. Protection circuitry is included to increase device reliability: thermal and under-voltage shutdown, with a status feedback terminal for use when any error condition is encountered.
The high switching frequency of the TPA032D02 allows the output filter to consist of three small capacitors and two small inductors per channel. The high switching frequency of TPA032D01 also allows for good THD+N performance. The TPA032D02 is offered in the thermally enhanced 48-pin PowerPAD TSSOP surface-mount package (designator DCA).
