20-W Stereo Digital Audio Power Amplifier With EQ And DRC

The TAS5706 is a 20-W, efficient, digital Audio power Amplifier for driving stereo bridged-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, accepting 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 subwoofer or Headphone PWM outputs. The TAS5706 is a slave-only device receiving all Clocks from external sources. The TAS5706 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. By Texas Instruments
