TAS5704

illustrate

The TAS5704 is a 20-watt, high-efficiency, digitally driven audio power amplifier for stereo bridged speakers. Two serial data inputs allow processing of up to four discrete audio channels and seamless integration into a wide range of input data and clock frequencies accepted by most digitally accepted audio processors. A hardware-configured data channel allows these channels to be routed to the internal speaker driver or to output a subwoofer output via PWM.

The TAS5704 was the only device for a slave to receive all clocks from external sources. The TAS5704 operates at 384 kHz switching speeds of 32-, 48-, 96-, and 192 kHz and switches at 352.8 kHz for data transfer rates of 44.1-, 88.2-, and 176.4 kHz. 8 × sampling combined with a fourth-order noise shaper provides a unit noise substrate from 20 Hz and an excellent dynamic range of 20 kHz.

characteristic
