Product Summary

The ADS7822U is a 12-bit sampling analog-to-digital (A/D) converter with ensured specifications over a 2.7V to 5.25V supply range. The ADS7822U 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. The applications of the ADS7822U include battery-operated systems, remote data acquisition, isolated data acquisition, simultaneous sampling, multi-channel systems.

Parametrics
