Texas Instruments TAS5701

the tas5701 is a 20-w efficient digital audio power amplifier for driving stereo bridge-tied speakers. two serial data inputs support up to 3 discrete audio channels. the sdin1 input is routed to the internal left and right outputs. the sdin2 input is dedicated to the sub_pwm outputs. the tas5701 is a clock slave-only device receiving clocks from external sources. the tas5701 operates at a 384-khz switching rate for 32- 48- 96- and 192-khz data and 352.8-khz switching rate 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.
