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
The device is suitable for portable, commercial, industrial, and
automotive applications.
