10-Bit, 40MHz Sampling  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
NO MISSING CODES  
INTERNAL REFERENCE  
LOW POWER: 380mW  
HIGH SNR: 58dB  
The ADS821 is a low-power, monolithic 10-bit, 40MHz 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 TRACK-AND-HOLD  
The ADS821 employs digital error correction to provide  
excellent Nyquist differential linearity performance for de-  
manding imaging applications. Its low distortion, high SNR,  
and high oversampling capability give it the extra margin  
needed for telecommunications and video applications.  
APPLICATIONS  
VIDEO DIGITIZING  
ULTRASOUND IMAGING  
GAMMA CAMERAS  
SET-TOP BOXES  
This high-performance converter is specified for AC and DC-  
performance at a 40MHz sampling rate. The ADS821 is  
available in an SO-28 package.
