Description
WM8761 24-bit 192 kHz Stereo DAC 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-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. FEATURES Stereo DAC Audio Performance - 100dB SNR (‘A’ weighted @ 48kHz) - -90dB THD DAC Sampling Frequency: 8kHz – 192kHz Pin Selectable Audio Data Interface Format - 16 to 24-bit I2S, 24-bit Right Justified or DSP 2.7V - 5.5V Supply Operation 14-pin SOIC Package Pin Compatible with WM8725 & WM8726 APPLICATIONS DVD Players Home Theatre Systems Digital TV Digital Set Top Boxes BLOCK DIAGRAM FORMAT MUTE DEEMPH BCKIN LRCIN DIN CONTROL INTERFACE WM8761 AUDIO INTERFACE MUTE MUTE DIGITAL FILTERS SIGMA DELTA MODULATOR SIGMA DELTA MODULATOR DAC DAC LOW PASS FILTER VOUTR LOW PASS FILTER VOUTL CAP MCLK VDD GND http://www.c...
