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 V_CC

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.
