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 W 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 V
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.
