TAS5711

illustrate

The TAS5711 is a 20-watt, high-efficiency, digitally driven stereo bridge speaker audio power amplifier. One serial data input allows processing of up to two independent audio channels and seamless integration into most digital audio processors and MPEG decoders. The device accepts input data and various data rates. A fully programmable data path routes these internal speaker driver channels.

The TAS5711 is an I²of slaves, the only device that receives all clocks from external sources. The TAS5711 operates between a PWM carrier with a switching frequency of 384 kHz and a switching frequency of 352 kHz depending on the input sampling rate. Oversampling combined with a fourth-order noise shaper provides a noise floor in units from 20 Hz and excellent dynamic range of 20 kHz.
