Description

The WM8764 are multi-channel audio DACs ideal for DVD and surround sound processing applications for home hi-fi, automotive and other audio visual equipment.

Three stereo 24-bit multi-bit sigma delta DACs of the WM8764 are used with oversampling digital interpolation filters. Digital audio input word lengths from 16-32 bits and sampling rates from 8kHz to 192kHz are supported.

The audio data interface supports either 16-24-bit I2S, 16- 24-bit left justified, or 24-bit right justified digital audio formats.

The WM8764 are controlled directly using the hardware interface. All members of the family are available in a 20-pin SSOP.
