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.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

APPLICATIONS INFORMATION
The ADCMP361 is a low power comparator with a build in
400mV reference that operates from 1.7V to 5.5V. The
comparators are approx 0.8% accurate with a built in hysteresis
of approx 6.5mV. The outputs are open drain capable of sinking
40mA.
COMPARATORS AND INTERNAL REFERENCE
The comparators has one input available externally and the
other input is connected internally to the 400mV reference. The
rising input threshold voltage of the comparators is designed to
be equal to that of the reference (i.e.≈400mV).
ADDING HYSTERESIS
To prevent oscillations at the output caused by noise or slowly
moving signals passing the switching threshold, each
comparator has built-in hysteresis of approximately 6.5mV.
Positive feedback can be used to adjust hysteresis.
OUTPUTS
The ADCMP361 has both inverting and noninverting outputs
available to provide a more flexible solution in applications
where the user may need to utilize the comparator in either
inverting or noninverting modes.
