How does a comparator circuit work
WebA comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is … WebIn general, the voltage comparator circuit accepts two voltages as inputs and produces one of two distinct output voltages depending on the relative values of the two inputs. During …

WebDec 13, 2024 · Many comparators have open-collector outputs so you can parallel them. This is useful in window-comparator applications. This means that when the inverting terminal voltage is greater, the load connected to output can be powered on. If V- > V+ then the output pulls low. A load connected between V CC and the output will turn on. WebApr 11, 2024 · How does comparator work? The comparator is derived from the operational amplifier, and the comparator circuit can be thought of as an operational amplifier application circuit. Special comparator integrated circuits have been developed due to the widespread use of comparator circuits.
