TAS5782M - 30-W, Digital Input, Stereo, Closed-Loop Class-D Amplifier with 96-kHz Flexible Processing

The TAS5782M deviceis a high-performance, stereo closed-loop Class-D amplifier with integrated audio processor with upto 96-kHz architecture. To convert from digital to analog, the device uses a high performance DACwith Burr Brown™ audio technology.It requires only two power supplies: one DVDD for low-voltage circuitry and one PVDD forhigh-voltage circuitry. It is controlled by a software control port using standardI²C communication.

An optimal mix of thermal performance and device cost is provided in the 90 mΩr_DS(on) of the output MOSFETs. Additionally, a thermally enhanced 48-PinTSSOP provides excellent operation in the elevated ambient temperatures found in modern consumerelectronic devices.
