Overview
w WM8714 24-bit, 96kHz Stereo DAC DESCRIPTION The WM8714 is a high performance stereo DAC designed for audio applications such as DVD, home theatre systems, and digital TV.
The WM8714 supports data input word lengths from 16 to 24-bits and sampling rates up to 96kHz.
The WM8714 consists of a serial interface port, digital interpolation filters, multi-bit sigma delta modulators and stereo DAC in a 14-pin SOIC package.
The WM8714 has a hardware control interface for selection of audio data interface format, mute and de-emphasis.
The WM8714 supports I2S, and right Justified audio data interfaces.
The WM8714 is an ideal device to interface to AC-3, DTS, and MPEG audio decoders for surround sound applications, or for use in DVD players.
