Hey guys,
I have a question about comparators I have 230 to 9v step down transformer and lm339. I want to compare positive and negative voltage. Does anyone know of a LM399 IC ?
Input voltage is 230v AC for transformer. I measure the output voltage of transformer is 8.5 aprpx
I have given 5v Dc supply to pin number 3 of IC and pin 12 is connected to ground
positive of transformer connected to pin 5
Negative of transformer connected to pin 4
I am measuring output voltage of comprator 1 but it show only 0 volt. Why it is not showing output voltage
