Preliminary Technical Data

ADCMP361

Rev. PrB | Page 11 of 13

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.
