TAS5782M (ACTIVE)

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

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

Description

The TAS5782M device is a high-performance, stereo closed-loop Class-D amplifier with integrated audio processor with up to 96-kHz architecture. To convert from digital to analog, the device uses a high performance DAC with Burr Brown™ audio technology. It requires only two power supplies: one DVDD for low-voltage circuitry and one PVDD for high-voltage circuitry. It is controlled by a software control port using standard I2C communication.

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