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.
