WebAug 18, 2024 · (2) In general speaking, the comparator is an open-loop application of the op amp, but the comparator is designed for voltage threshold comparison. The required comparison threshold must be accurate, and the rise or fall time of output edge after comparison should be short. WebWhat is op amp comparator circuit? Op-amp window comparators are a type of voltage comparator circuit which uses two op- amp comparators to produce a two-state output that indicates whether or not the input voltage is within a particular range or window of values by using two reference voltages. An upper reference voltage and a lower reference voltage.
