TAS5707 具有 EQ 和 DRC（软件控制）的 20W 立体声数字音频功率放大器

The TAS5707 is a 20-W, efficient, digital-audio power amplifier for driving stereo bridge-tied speakers. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers.

The TAS5707 is a slave-only device receiving all clocks from external sources. The TAS5707 operates with a PWM carrier between a 384-kHz switching rate and 352-KHz switching rate, depending on the input sample rate. Oversampling combined with a fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.
