![]() ![]() The third comparator 1 st input is on pin 8 and 2 nd input is on pin 9,the output of this comparator is on pin 13, and the last comparator 1 st input is pin 10 and 2 nd input is on pin 11,the output is on pin 14. Now jump on other side of LM339 comparator. You that that in diagram there are four comparators in LM339, the first comparator 1 st input is on pin 4 and 2 nd input is on pin 5 and the output of these input at pin 2, the second comparator 1 st input is on pin 6 and 2 nd input is on pin 7 and the other is on pin 1. Now discuses about the working of the comparator, as you know that the comparator join two input and give one output. There is another picture for your understanding and this picture also defines the working for the LM339 comparator.Īs you remember that I am say about curve on comparator and very most left pin is the first pin and goes no. The dot is representing first pin and the counting process is same like curve method. When you identify this curve then very most left pin you can start count from there are count left to right. You see curve shape on the LM339 comparator. There is no dot the pick the lm339 comparator. ![]() There you can see a dot on lm339 comparator. It is two simple first we have to see the picture of LM339 comparator. ![]() The question is raise ” How we can identify the pin”. ![]() It has 14 pins and each pin have different functionality. First we discuss about the working of the lm339 comparator. ![]()
