1 / 12 page ADS7822 DESCRIPTION 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 60 µW at 7.5kHz. 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 within the range of 50mV to VCC. 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. 12-Bit High Speed 2.7V microPower Sampling ANALOG-TO-DIGITAL CONVERTER ® ©1996 Burr-Brown Corporation PDS-1358C Printed in U.S.A., May, 2000 International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
