12-Bit High Speed 2.7V microPower Sampling  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
● 75kHz SAMPLING RATE  
The ADS7822 is a 12-bit sampling analog-to-digital  
converter (A/D) with guaranteed specifications over a  
2.7V to 3.6V supply range. It requires very little power  
even when operating at the full 75kHz 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.  
● MICRO POWER:  
0.54mW at 75kHz  
0.06mW at 7.5kHz  
● POWER DOWN: 3µA max  
● MINI-DIP-8, SOIC-8, AND MSOP-8  
● DIFFERENTIAL INPUT  
The ADS7822 also features operation from 2.0V to  
5V, a synchronous serial interface, and a differential  
input. The reference voltage can be set to any level  
● SERIAL INTERFACE  
within the range of 50mV to VCC  
.
APPLICATIONS  
● BATTERY OPERATED SYSTEMS  
● REMOTE DATA ACQUISITION  
● ISOLATED DATA ACQUISITION  
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  
multi-channel systems, and isolated data acquisition.  
The ADS7822 is available in a plastic mini-DIP-8, an  
SOIC-8, or an MSOP-8 package.
