The TAS5709 is a 20-watt, high-efficiency, digital audio power driven stereo bridged speaker amplifier. One serial data input allows processing of up to two independent audio channels and seamless integration into most digital audio processors and MPEG decoders. The device accepts input data and various data rates. A fully programmable data path routes these internal speaker driver channels.

The TAS5709 is a slave's only device that receives all clocks from external sources. Operating TAS5709 has a switching frequency of 384 kHz and a switching frequency of 352 kHz, the input sampling rate depends on the PWM carrier. Oversampling combined with a fourth-order noise shaper provides a noise floor in units from 20 Hz and excellent dynamic range of 20 kHz.
