One Automatic Rate Detection serial data input allows processing of up to two – Surface Mount, 48-Pin, 7-mm × 7-mm discrete audio channels and seamless integration to HTQFP Package most digital audio processors and MPEG decoders. – Thermal and Short-Circuit Protection The device accepts a wide range of input data and data rates. A fully programmable data path routes – Support for AD or BD Mode these channels to the internal speaker drivers. The TAS5711 is an I 2S 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. Oversampling combined with a fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.
