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.

FEATURES
• Gain range from -111.5dB to +15.5dB
• 0.5dB Gain step size
• Total Harmonic Distortion 0.001% (100dB) typical
• Crosstalk -110dB typical
• Input signals up to ±18V
• Zero Detection for Gain Changes
• Hardware and Software Mute
• Power On/Off Transient Suppression

APPLICATIONS
• Audio Amplifiers
• Consumer Audio / Entertainment Systems
• Mixing Desks
• Audio Recording Equipment
