Stereo Low Power 96kHz ADC
DESCRIPTION
The WM8783 is a compact, low cost ADC designed for set-top
boxes and DVD applications.
Stereo analogue inputs accept 1Vrms line level inputs; the Hi-Fi
ADCs output 24-bit stereo data on the I2S digital audio
interface.
Sample rates from 8kHz to 96kHz are supported; this is
configured automatically according to the external master clock
(MCLK) frequency.
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 WM8783 is supplied in an 8-pin SOIC package.
