Texas Instruments TAS5782M Closed-Loop Class-D Amplifier
Texas Instruments TAS5782M Closed-Loop Class-D Amplifier is a high-performance, stereo Class-D amplifier with an integrated audio processor with up to 96kHz architecture. The device uses a high-performance DAC with Burr Brown™ audio technology to convert from digital to analog. It requires only two power supplies: one DVDD for low-voltage circuitry and one PVDD for high-voltage circuitry. The Texas Instruments TAS5782M is controlled by a software control port using standard I2C communication. An optimal thermal performance and device cost mix is provided in the 90mΩ rDS(on) of the output MOSFETs. Additionally, a thermally enhanced 48-Pin TSSOP package provides excellent operation in the elevated ambient temperatures in modern consumer electronic devices.Features
