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.
