I can't figure out why my comparator is not working, so that probably means I'm doing something wrong . In the most simplistic of comparator circuits, I thought I could give my LM2903 a
VCC = 13.75vDC
VEE = battery -
inverting pin 1 = 6.92vDC
non inverting pin 1 = switched 13.75vDC
When I switch the non inverting pin to +13.75vDC, output pin 1 does not swing to near VCC, it stays at near VEE (around 0.5vDC) . What am I doing wrong? I read through this thread http://forum.allaboutcircuits.com/showthread.php?t=6760 and from reading that I'm doing things correctly? Any ideas?
Thanks for reading!
