DESCRIPTION
The WM8772 is a multi-channel audio codec ideal for DVD and surround sound processing applications for home hi-fi, automotive and other audio visual equipment.
A stereo 24-bit multi-bit sigma delta ADC is used. Digital audio output word lengths from 16-32 bits and sampling rates from 32kHz to 96kHz are supported. The 32-lead version allows separate ADC and DAC samples rates.
