The TAS5705 is a 20-W, efficient, digital audio power amplifier for driving stereo bridge-tied speakers. Two serial data inputs allow processing of up to four discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a wide range of input data and clock rates. A fully programmable data path allows these channels to be routed to the internal speaker drivers or output via the line-level subwoofer or headphone PWM outputs.

The TAS5705 is a slave-only device receiving clocks from external sources. The TAS5705 operates at a 384-kHz switching rate for 32-, 48-, 96-,and 192-kHz data and 352.8-kHz switching rate for 44.1-, 88.2- and 176.4-kHz data. The 8× oversampling combined with the fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.
