1 / 36 page  w WM8766 24-bit, 192kHz 6-Channel DAC WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at http://www.wolfsonmicro.com/enews/ Production Data, July 2005, 4.1 Copyright 2005 Wolfson Microelectronics plc DESCRIPTION The WM8766 is a multi-channel audio DAC ideal for DVD and surround sound processing applications for home hi-fi, automotive and other audio visual equipment. Three stereo 24-bit multi-bit sigma delta DACs are used with oversampling digital interpolation filters. Digital audio input word lengths from 16-32 bits and sampling rates from 8kHz to 192kHz are supported. Each DAC channel has independent digital volume and mute control. The audio data interface supports I 2S, left justified, right justified and DSP digital audio formats The device is controlled via a 3 wire serial interface or directly using the hardware interface. These interfaces provide access to features including channel selection, volume controls, mutes, de-emphasis and power management facilities. The device is available in a 28-lead SSOP. FEATURES • 6-Channel DAC • Audio Performance − 103dB SNR (‘A’ weighted @ 48kHz) DAC • DAC Sampling Frequency: 8kHz – 192kHz • 3-Wire SPI Serial or Hardware Control Interface • Programmable Audio Data Interface Modes − I 2S, Left, Right Justified or DSP − 16/20/24/32 bit Word Lengths • Three Independent stereo DAC outputs with independent digital volume controls • Master or Slave Audio Data Interface • 2.7V to 5.5V Analogue, 2.7V to 3.6V Digital supply Operation • 28 lead SSOP Package APPLICATIONS • DVD Players • Surround Sound AV Processors and Hi-Fi systems • Automotive Audio BLOCK DIAGRAM |
