  1. voltage - How exactly does a comparator work? - Electrical …

    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 …

  2. Can someone explain how this transistor comparator works?

    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 …

  3. Understanding this comparator circuit for AC voltage protection

    Jul 15, 2019 · The circuit shown below is taken from this whole design. I understand the main idea. They want to measure some voltage condition and trigger something else with the …

  4. operational amplifier - LM358 comparator circuit - Electrical ...

    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 …

  5. How can I make an ideal comparator in LTspice?

    Oct 1, 2017 · For fast simulations I sometimes need an ideal comparator. I guess it is not a built-in component. How can it be implemented by ideal sources or VCVS ect.?

  6. What is the difference between a general comparator and a …

    6 I notice that the LM339 quad comparator comes in 2 different varietys: general-purpose and differential. Besides a big difference in price, what is the difference between the two? …

  7. operational amplifier - Common Mode Range in comparators

    Dec 5, 2024 · What do we mean by Common Mode Voltage Range in comparators, and how does it help in selection of a comparator for any application?

  8. Why do they usually make comparators open collector?

    Aug 21, 2014 · The main reason for using open-collector is so that several comparators can have their output connected together in a wired OR gate. All the open collectors can be tied together …

  9. comparator - Unused pins on a LM339 quad op amp - Electrical ...

    May 6, 2025 · Tying the inputs together seems to be a recipe for hammering the output back and forth in the presence of noise. From LordTeddy's answer below, tying the inputs t the negative …

  10. Difference between differential op amp and comparator

    A comparator returns a boolean/digital value: 0 if input A is higher than input B, 1 otherwise. A differential op-amp outputs an analogue value: the difference between the inputs, multiplied by …
