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.
