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.

The closed-loop architecture of the TAS5704 provides several benefits. The high power supply rejection enables superior audio performance from a noisy, low cost supply. The high damping factor allows tighter control over speaker movement resulting in an improved bass response. Finally, switching edge rate control lowers EMC emissions without sacrificing audio performance.
