GENERAL DESCRIPTION
The ADCMP361 is a single low power, low voltage comparator
with a 400mV reference in the 5-lead SOT-23 package.
Operating within a supply range of 1.7V to 5.5V, the device
only draw 6.5µA typical, making it ideal for low voltage system
monitoring and portable applications. Hysteresis is included in
the comparators to insure stable output operation. The
comparator has only one input available externally, the other
input is connected internally to the reference. The comparator
has both an inverting and a noninverting output. The output
stage sinking capability guaranteed greater than 5mA over
temperature.
Available in commercial, industrial and automotive
temperature ranges.
