产品概述

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.
