DESCRIPTION

The WM8782 is a high performance, low cost stereo audio

ADC designed for recordable media applications.

The device offers stereo line level inputs along with two

control input pins (FORMAT, IWL) to allow operation of the

audio interface in three industry standard modes. An

internal op-amp is integrated on the front end of the chip to

accommodate analogue input signals greater than 1Vrms.

The device also has a high pass filter to remove residual

DC offsets.

WM8782 offers Master or Slave mode clocking schemes.

A control input pin M/S is used to allow Slave mode

operation or Master mode operation. A stereo 24-bit multi-

bit sigma-delta ADC is used with 128x, 64x or 32x over-

sampling, according to sample rate. Digital audio output

word lengths from 16-24 bits and sampling rates from 8kHz

to 192kHz are supported.

The device is a hardware controlled device and is supplied

in a 20-lead SSOP package.

The device is available over a functional temperature range of

-40

C to +85C
