24-bit 192kHz Stereo DAC
WM8761
DESCRIPTION
The WM8761 is a high performance stereo DAC designed
for audio applications such as DVD, home theatre systems,
and digital TV. The WM8761 supports data input word
lengths from 16 to 24-bits and sampling rates up to 192kHz.
The WM8761 consists of a serial interface port, digital
interpolation filters, multi-bit sigma delta modulators and
stereo DAC in a 14-pin SOIC package.
The WM8761 has a hardware control interface for selection
of audio data interface format, mute and de-emphasis. The
WM8761 supports I2S, right justified or DSP interfaces.
The WM8761 is an ideal device to interface to AC-3ï¤,
DTSï¤, 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.
