2、 AMP IC TAS5711
The TAS5711 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 TAS5711 is an I2S slave-only device receiving all clocks from external
sources. The TAS5711
operates with a PWM carrier between 384-kHz switching rate and 352-KHz
switching rate depending on the input sample rate. Over sampling combined
with a fourth-order noise shaper provides a flat noise floor and excellent
dynamic range from 20 Hz to 20 kHz.
