Apr 10, 2015 · The circuit is a comparator and can be remarkably useful more or less as shown. I have used a circuit essentially the same as that in production equipment to meet a requirement which was …

Apr 12, 2015 · How exactly does a comparator work? Comparators have many uses and its concept is not too hard to grasp. What I don't understand however is how exactly it compares two voltages. …

Oct 16, 2024 · How to explore it The best way to understand this idea is to try implementing hysteresis step by step in your op-amp inverting comparator circuit. Let's simulate each step with a separate …

Jan 21, 2025 · I drew the following circuit using LM358 opamp in order to understand the comparator behavior. I have few questions regarding the circuit below: How should I wire the unused opamp? …

Dec 16, 2024 · Don't bother: a low voltage cutoff based on the total battery voltage is useless because it doesn't protect the Li-ion battery. By the time it shuts off, one of the cells is likely to be over …

Aug 23, 2025 · The LM311 device is a comparator with an uncommited transistor output. This means that the output pin needs a pull-up resistor so that it can create a voltage signal and also pin 1 (the …

What is the difference between a differential op amp and a comparator? I know a comparator can only give me two values (the supply values). The differential op amp amplifies the difference between...

Jan 9, 2024 · If you examine 98% of circuits online that include hysteresis for a comparator, they always implement the hysteresis on the non-inverting input, like so: This is easy enough to calculate. …

May 10, 2023 · I am trying to simulate the following comparator circuit with LTspice: The LM311 comparator was intended to be used with hysteresis, same as the circuit shown in this graph …

Apr 12, 2023 · Your circuit, even with an ideal op-amp will provide asymmetrical hysteresis and is that what you want? If you are looking for a precise comparator then, inevitably, as the inputs get close …
