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 requirement which was …
Comparator with hysteresis; what resistors go where?
Apr 11, 2023 · The comparator does it during the transition with the help of the positive feedback. What positive feedback is This is positive feedback "out of control" or as they call it, "self-reinforcing …
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 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...
