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 of input data and data rates. A fully programmable data 

path routes these channels to the internal speaker drivers. 

The  TAS5717/9  is  a  slave-only  device  receiving  all  clocks  from  external  sources.  The 

TAS5717/TAS5719  operates with  a  PWM  carrier between a  384-kHz  switching rate  and  a 

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.
