DESCRIPTION

FEATURES

•

24 bit Stereo DAC

The WM8718 is a high performance differential stereo DAC

designed for audio applications such as DVD, home theatre

systems and digital TV. The WM8718 supports PCM data

input word lengths from 16 to 32-bits and sampling rates up

to 192kHz. The WM8718 consists of a serial interface port,

digital interpolation filters, multi-bit sigma delta modulators
