8-Bit, 80MHz Sampling  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
HIGH SNR: 49dB  
DESCRIPTION  
The ADS831 is a pipeline, CMOS analog-to-digital con-  
verter that operates from a single +5V power supply. This  
converter provides excellent performance with a single-  
ended input and can be operated with a differential input  
for added spurious performance. This high performance  
converter includes an 8-bit quantizer, high bandwidth  
track/hold, and a high accuracy internal reference. It also  
allows for the user to disable the internal reference and  
utilize external references. This external reference option  
provides excellent gain and offset matching when used in  
multi-channel applications or in applications where DC full  
scale range adjustment is required.  
INTERNAL/EXTERNAL REFERENCE  
OPTION  
SINGLE-ENDED OR  
DIFFERENTIAL ANALOG INPUT  
PROGRAMMABLE INPUT RANGE:  
1Vp-p /2Vp-p  
LOW POWER: 275mW  
LOW DNL: 0.35LSB  
SINGLE +5V SUPPLY OPERATION  
20-PIN SSOP PACKAGE  
The ADS831 employs digital error correction techniques to  
provide excellent differential linearity for demanding im-  
aging applications. Its low distortion and high SNR give  
the extra margin needed for medical imaging, communica-  
tions, video, and test instrumentation.  
APPLICATIONS  
MEDICAL IMAGING  
The ADS831 is specified at a maximum sampling fre-  
quency of 80MHz and a single-ended input range of 1.5V  
to 3.5V. The ADS831 is available in a 20-lead SSOP  
package and is pin-for-pin compatible with the 8-bit, 60MHz  
ADS830.
