SBAS037B – DECEMBER 1995 – REVISED FEBRUARY 2005  
10-Bit, 20MHz Sampling  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
NO MISSING CODES  
The ADS820 is a low-power, monolithic 10-bit, 20MHz Ana-  
log-to-Digital (A/D) converter utilizing a small geometry CMOS  
process. This complete converter includes a 10-bit quantizer  
with internal track-and-hold, reference, and a power down  
feature. It operates from a single +5V power supply and can  
be configured to accept either differential or single-ended  
input signals.  
INTERNAL REFERENCE  
LOW DIFFERENTIAL LINEARITY ERROR:  
0.2LSB  
LOW POWER: 195mW  
HIGH SNR: 60dB  
WIDEBAND TRACK/HOLD: 65MHz  
The ADS820 employs digital error correction to provide excel-  
lent Nyquist differential linearity performance for demanding  
imaging applications. Its low distortion, high SNR, and high  
oversampling capability give it the extra margin needed for  
telecommunications and video applications.  
APPLICATIONS  
SET-TOP BOXES  
CABLE MODEMS  
VIDEO DIGITIZING  
This high performance converter is specified for AC and  
DC-performance at a 20MHz sampling rate. The ADS820  
is available in an SO-28 package.
