Audio/PWM Processing
The TAS5717/TAS5719 is a 10-W/15-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
