200kHz Sampling Rate  
•
microPower:  
The ADS7822 is a 12-bit sampling analog-to-digital  
(A/D) converter with ensured specifications over a  
2.7V to 5.25V supply range. It requires very little  
power even when operating at the full 200kHz rate. At  
lower conversion rates, the high speed of the device  
enables it to spend most of its time in the  
power-down mode—the power dissipation is less  
than 60μW at 7.5kHz.  
1.6mW at 200kHz  
0.54mW at 75kHz  
0.06mW at 7.5kHz

Pseudo-Differential Input  
Serial Interface  
The ADS7822 also features operation from 2.0V to  
5V,  
pseudo-differential input. The reference voltage can  
be set to any level within the range of 50mV to VCC

Battery-Operated Systems  
Remote Data Acquisition  
Isolated Data Acquisition  
Simultaneous Sampling, Multichannel Systems  
Ultra low power and small size make the ADS7822  
ideal for battery-operated systems. It is also a perfect  
fit for remote data-acquisition modules, simultaneous  
multichannel systems, and isolated data acquisition.  
The ADS7822 is available in a plastic mini-DIP-8, an  
SO-8, or an MSOP-8 package.
