24-Bit, 192kHz Stereo ADC  
DESCRIPTION  
FEATURES  
SNR 100dB (‘A’ weighted @ 48kHz)  
The WM8782 is a high performance, low cost stereo audio  
ADC designed for recordable media applications.  
THD -93dB (at –1dB)  
Sampling Frequency: 8 – 192kHz  
Master or Slave Clocking Mode  
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  
System Clock (MCLK): 128fs, 192fs, 256fs, 384fs, 512fs,  
768fs  
accommodate analogue input signals greater than 1Vrms  
.
-
Audio Data Interface Modes  
The device also has a high pass filter to remove residual  
DC offsets.  
16-24 bit I2S, 16-24 bit Left, 16-24 bit Right Justified  
Supply Voltages  
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.  
-
-
Analogue: 2.7 to 5.5V  
Digital core: 2.7V to 3.6V  
20-lead SSOP or 20-lead TSSOP package  
Accelerated Lifetime Screened Devices available.  
APPLICATIONS  
Recordable DVD Players  
Personal Video Recorders  
STB  
Studio Audio Processing Equipment  
Automotive  
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  
-40C to +85C
