Description

The WM8782 is a high performance, low cost stereo audioADC designed for recordable media applications.

The WM8782 offers stereo line level inputs along with twocontrol input pins (FORMAT, IWL) to allow operation of theaudio interface in three industry standard modes. Aninternal op-amp is integrated on the front end of the chip toaccommodate analogue input signals greater than 1Vrms.The device also has a high pass filter to remove residualDC offsets.

WM8782 offers Master or Slave mode clocking schemes.A control input pin M/S is used to allow Slave modeoperation or Master mode operation. A stereo 24-bit multibitsigma-delta ADC is used with 128x, 64x or 32x oversampling,according to sample rate. Digital audio outputword lengths from 16-24 bits and sampling rates from8kHz to 192kHz are supported.

The WM8782 is a hardware controlled device and is supplied
in a 20-SSOP package.
