GENERAL DESCRIPTION

The ADCMP361 is a single low power, high accuracy compara-

tor with a 400 mV reference in a 5-lead SOT-23 package. The

internal 400 mV reference provides the ability to monitor low

voltage supplies. The device operates on a supply voltage from

1.7 V to 5.5 V and only draws 6.5 μA typical, making it suitable

for low power system monitoring and portable applications.

Hysteresis is included in the comparators.

There are dual open-drain outputs to enable the comparator

and reference circuit to be used in an inverting or noninverting

configuration. The outputs can be pulled to any voltage up to a

maximum of 5.5 V. The output stage is guaranteed to sink greater

than 5 mA over temperature
