WM8782A  
w
24-Bit, 192kHz Stereo ADC  
DESCRIPTION  
FEATURES  
SNR 100dB (‘A’ weighted @ 48kHz)  
The WM8782A is a high performance, low cost stereo  
audio ADC designed for recordable media applications.  
THD -93dB (at –1dB)  
Sampling Frequency: 8 – 192kHz  
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  
The device also has a high pass filter to remove residual  
DC offsets.  
.
Audio Data Interface Modes  
-
16-24 bit I2S, 16-24 bit Left, 16-24 bit Right Justified  
Supply Voltages  
WM8782A offers a Slave mode clocking scheme. 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 package  
Accelerated Lifetime Screened Devices available.  
The device is a hardware controlled device and is supplied  
in a 20-lead SSOP.  
APPLICATIONS  
Recordable DVD Players  
Personal Video Recorders  
STB  
Studio Audio Processing Equipment  
Automotive  
The device is available over a functional temperature range of  
-40°C to +85°C
