The TAS5704 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 accepTIng a wide range of input data and clock rates. A hardware configurable data path allows these channels to be routed to the internal speaker drivers or output via the subwoofer PWM outputs.
The TAS5704 is a slave-only device receiving all clocks from external sources. The TAS5704 operates at a 384-kHz switching rate for 32-, 48-, 96-, and 192-kHz data, and at a 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.
