10-W Stereo Class D Audio Power Amplifier

The TPA032D04 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 TPA032D04 to be configured as a bridge-tied load (BTL) Amplifier capable of delivering up to 10 W of continuous average power into a 4- 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. Included is a Class-AB Headphone Amplifier with Interface Logic to select between the two modes of operation. Only one Amplifier is active at any given time, and the other is in power-saving sleep mode. Also, a chip-level shutdown control is provided to limit total supply current to 20 uA, making the device ideal for battery-powered applications. The output stage 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 TPA032D04 allows the output Filter to consist of three small capacitors and two small inductors per channel. The high switching frequency also allows for good THD+N performance. The TPA032D04 is offered in the thermally enhanced 48-pin PowerPADTM TSSOP surface-mount package (designator DCA). NOTE A: LPVDD, RPVDD, and PVDD are externally connected. AGND and PGND are externally connected. By Texas Instruments
