DESCRIPTION

The  WM8816  is  a  highly  linear  stereo  volume  control  for audio systems. The design is based on resistor chains with external  op-amps,  which  provides  flexibility  for  the  supply voltage, signal swing, noise floor and cost optimisation. The gain  of  each  channel  can  be  independently  programmed from  -111.5dB  to  +15.5dB  through  a  digital  serial  control interface.
