DESCRIPTION
The WM8773 is a high performance, stereo audio ADC with
an 8 channel input selector. The WM8773 is ideal for
digitising multiple analogue sources for 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 with an
eight stereo channel input selector. Each channel has
analogue domain mute and programmable gain control.
Digital audio output word lengths from 16-32 bits and
sampling rates from 8kHz to 96kHz are supported.
The audio data interface supports I
justified and DSP digital audio formats.

The device is controlled via a 3 wire serial interface. The
interface provides access to all features including channel
selection, volume controls, mutes, de-emphasis and power
management facilities. The device is available in a 64-pin
TQFP package.
