DESCRIPTION

The WM8775 is a high performance, stereo audio ADC

with a 4 channel input mixer. The WM8775 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 a

four stereo channel input selector. Each channel has

programmable gain control. Digital audio output word

lengths from 16-32 bits and sampling rates from 32kHz

to 96kHz are supported.

The audio data interface supports I

2S, left justified, right

justified and DSP digital audio formats.

The device is controlled via a 2 or 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 28-pin SSOP package. The

WM8775 is software compatible with the WM8776.
