WM8783 w Stereo Low Power 96kHz ADC DESCRIPTION FEATURES Hi-fi audio ADC (96dB SNR - A weighted) The WM8783 is a compact, low cost ADC designed for set-top 2 analogue audio inputs boxes and DVD applications. I2S digital audio interface - sample rates 8kHz to 96kHz Stereo analogue inputs accept 1Vrms line level inputs the Hi-Fi Automatic clocking configuration from MCLK and LRCLK ADCs output 24-bit stereo data on the I2S digital audio Integrated voltage reference circuits interface. 8-pin SOIC package Sample rates from 8kHz to 96kHz are supported this is configured automatically according to the external master clock (MCLK) frequency. APPLICATIONS A power on reset (POR) circuit ensures correct start-up and LCD televisions shut-down. The device is held in reset when MCLK is not Set-top boxes (STB) present, offering a low-power standby state. DVD recorders The WM8783 is supplied in an 8-pin SOIC package.
