1 / 16 page  w WM8727 24-bit 192kHz Stereo DAC WOLFSON MICROELECTRONICS plc www.wolfsonmicro.com Production Data, April 2004, Rev 4.1 Copyright 2004 Wolfson Microelectronics plc DESCRIPTION The WM8727 is a high performance stereo DAC designed for audio applications such as DVD, home theatre systems, and digital TV. The WM8727 supports data input word lengths from 16 to 24-bits and sampling rates up to 192kHz. The WM8727 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 WM8727 supports a 16-24-bit I 2S digital audio interface. The WM8727 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.
