GENERAL DESCRIPTION
The ADCMP370/ADCMP371 are general-purpose comparators
with input offset voltages of 9 mV (maximum) and low power
consumption, which make them ideal for battery-powered,
portable equipment.

The ADCMP371 has a push-pull output stage, while the
ADCMP370 has an open-drain output. The inputs on both
parts and the output on the ADCMP370 can tolerate voltages
up to 22 V, making them suitable for use as voltage detectors in
portable equipment.
The devices are available in space-efficient, 5-lead SC70
packaging.
