DESCRIPTION

The WM8726 is a high performance stereo DAC designed

for audio applications such as DVD, home theatre systems,

and digital TV. The WM8726 supports data input word

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

The WM8726 consists of a serial interface port, digital

interpolation filters, multi-bit sigma delta modulators and

stereo DAC.

The WM8726 has a hardware control interface for selection

of audio data interface format, mute and de-emphasis. The

WM8726 supports I

2S, right Justified or DSP interfaces.

The WM8726 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.

The WM8726 is available in a 14-lead SOIC package.
