10-Bit, 40MHz Sampling  
ANALOG-TO-DIGITAL CONVERTERS  
●
+3V OR +5V LOGIC I/O COMPATIBLE (ADS825)  
FEATURES  
● HIGH SNR: 60dB  
● POWER DOWN: 20mW  
● 28-LEAD SSOP PACKAGE  
● HIGH SFDR: 72dBFS

● SINGLE-ENDED OR  
FULLY DIFFERENTIAL ANALOG INPUT  
● PROGRAMMABLE INPUT RANGE  
● LOW DNL: 0.5LSB  
● SINGLE +5V SUPPLY OPERATION  
The ADS822 and ADS825 employ digital error correction tech-  
niques to provide excellent differential linearity for demanding  
imaging applications. Its low distortion and high SNR give the  
extra margin needed for medical imaging, communications,  
video, and test instrumentation. The ADS822 and ADS825 offer  
power dissipation of 190mW and also provide a power-down  
mode, thus reducing power dissipation to only 20mW. The  
ADS825 is +3V or +5V Logic I/O compatible.  
DESCRIPTION  
The ADS822 and ADS825 are pipeline, CMOS analog-to-digital  
converters that operate from a single +5V power supply. These  
converters provide excellent performance with a single-ended  
input and can be operated with a differential input for added  
spurious performance. These high-performance converters in-  
clude a 10-bit quantizer, high-bandwidth track-and-hold, and a  
high-accuracy internal reference. They also allow 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 applica-  
tions where full-scale range adjustment is required.  
The ADS822 and ADS825 are specified at a maximum sampling  
frequency of 40MHz and a single-ended input range of 1.5V to  
3.5V. The ADS822 and ADS825 are available in a 28-lead SSOP  
package and are pin-for-pin compatible with the 10-bit, 60MHz  
ADS823 and ADS826, and the 10-bit, 70MHz ADS824, provid-  
ing an upgrade path to higher sampling frequencies.
