24-bit 192kHz Stereo DAC

WM8762

DESCRIPTION

The WM8762 is a high performance stereo DAC designed

for audio applications such as DVD, home theatre systems,

and digital TV. The WM8762 supports data input word

lengths from 16 to 24-bits and sampling rates up to 192kHz.

The WM8762 consists of a serial interface port, digital

interpolation filters, multi-bit sigma delta modulators and

stereo DAC in a very small 8-pin SOIC package.

The WM8762 supports a 16-24-bit left justified digital audio

interface.

The WM8762 is an ideal device to interface to AC-3,

DTS, and MPEG audio decoders for surround sound

applications, or for use in DVD players, including supporting

the implementation of 2 channels at 192kHz for high-end

DVD-Audio applications.
