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 …
Detecting an open circuit by sensing current flow using a shunt …
This needn't run from +/-15V supplies providing you choose the right comparator or op-amp BUT watch out for leakage currents into the op-amp/comparator inputs if you are using large values …
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, …
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?
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 …
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 …
