I am new to comparators and I just found this LM339N in my washing machine and decided to take it out because I wanted it. Now I want to learn about comparators, so I have a couple really basic questions after doing a little research:
1) when V+ is greater than V- and the output goes high, is the is the high voltage VSS?
2) Now, if ground is 0 volts, which it usually is, how would you get V+ below it to make the output go low?
3) Does low=ground voltage
Thanks
