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 unused opamp? …
Can someone explain how this transistor comparator works?
Apr 10, 2015 · Extra Information: I want to use this 'comparator' in a circuit where I have a μ μ C being powered by a current limited ~2V regulator. Currently, if the voltage output of this regulator drops …
Comparator vs op-amp - Electrical Engineering Stack Exchange
Jun 21, 2021 · An op amp or true comparator operating in open loop can both be called comparators but quite often these comparators would be given some hysteresis (two threshold levels) by adding …
What is the difference between a general comparator and a differential ...
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? Specifically, I …
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.?
operational amplifier - Common Mode Range in comparators
Dec 5, 2024 · Common-mode voltage range (CMVR) is the range of common mode signals that an amplifier can process without losing linearity and can provide a reliable comparison output. In other …
Why do they usually make comparators open collector?
Aug 21, 2014 · The difference is that the comparator output is a logic output that can only be on or off, and the opamp output is analog. An open collector output is simple and flexible but relatively slow …
How to deal with strobe and balance pins of this comparator for single ...
I want to use this LM311 comparator with a single supply. But these are pins called balance and strobe which confuses me. What are these for? In a forum I read someone suggests pin 5 and pin 6 sho...
