DESCRIPTION

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.

The ADS7822 also features operation from 2.0V to

5V, a synchronous serial interface, and a

pseudo-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

multichannel systems, and isolated data acquisition.

The ADS7822 is available in a plastic mini-DIP-8, an

SO-8, or an MSOP-8 package.
