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 in a 14-lead SOIC package. 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.
