1 / 22 page  w WM8788 High Performance 24-bit Stereo ADC WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at http://www.wolfsonmicro.com/enews Preliminary Technical Data, December 2010, Rev 2.2 Copyright ©2010 Wolfson Microelectronics plc DESCRIPTION The WM8788 is a high performance 24-bit stereo ADC designed for LCD televisions, DVD, Blu-Ray and set-top box applications. A stereo pair of analogue inputs is provided; external resistors are used to configure the device for line level inputs at 1Vrms or for higher input signal levels. The Hi-Fi ADCs output 16, 20 or 24-bit stereo data on the digital audio interface. ADC sample rates from 8kHz to 192kHz are supported; Master Clock (MCLK) ratios of 128fs up to 768fs are possible (fs = sample rate). The digital audio interface operates in Master or Slave modes, and supports Right-justified, Left-justified and I2S modes, selectable using hardware control pins. The WM8788 is powered from a single 3.3V supply rail, connected to the AVDD and REFVDD pins. A power on reset (POR) circuit ensures correct start-up and shut-down. The device is held in reset when MCLK is not present, offering a low-power standby state. The WM8788 is supplied in a 16-pin TSSOP package.
