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? …
How to deal with strobe and balance pins of this comparator for …
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 …
Using a Zener for reference voltage - Electrical Engineering Stack …
I want to use a 9.1V Zener diode for a ref voltage into a op amp comparator so that when the battery voltage (11-12V DC) drops below 9.5V DC it will cut the supply to the circuit via a P …
Detecting an open circuit by sensing current flow using a shunt …
The approach I thought of was to put a small sense resistor between +5V and the load, and use a comparator to detect the voltage drop across the sense resistor. When current is flowing, there …
comparator - How to light an LED controlled by a photo-diode ...
I need to get an LED shining brightly when a photo-diode (in the local store it is sold as such, but of course it could be something else, as suggested in the answer of WhatRoughBeast) …
Difference between differential op amp and comparator
Oct 9, 2015 · 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, …
comparator - How can I modify this circuit for some hysteresis and ...
How can I add some hysteresis to this comparator without affecting the function of this circuit? Is there anything fundamentally wrong or missing with this design?
CMRR of Comparators - Electrical Engineering Stack Exchange
I have been looking around for the Common mode rejection ratio value on the datasheets for comparators but there don't have one. Why is this? This ratio is crucial in terms of choosing a …
From sine wave to square wave - Electrical Engineering Stack …
Jun 23, 2021 · I want to make a square wave generator with an LM311. I have a variable sine wave source from 1Hz to 16kHz. The amplitude can vary between 0.5V to 11.4V. I tried to use …
Smallest Voltage that a comparator can detect
Jan 10, 2014 · What is the smallest voltage a comparator can detect? Is it possible to set the reference voltage to a few millivolts, just above the noise margin for using a comparator circuit?
