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.
