Texas Instruments' 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.
