GENERAL DESCRIPTION

The ADCMP370/ADCMP371 are general purpose comparators

with input offset voltages of 6mV (max). High performance

over the -40°C to +125°C temperature range make them

suitable for use in automotive and other thermally harsh

applications, while low power consumption and space efficient

SC70 packaging make them ideal for battery powered portable

equipment.

The ADCMP371 has a push-pull output stage, while the

ADCMP370 has an open-drain output, which can be pulled as

high as 22V through an external resistor.
