Comparator using UA741CN
Version 1 - Last update: Oct 3, 2015

Reviewing my old electronics books I thought I would put together a simple comparator circuit using the UA741CN that is provided in this application. But I am currently having issues trying to get it to work. Am I missing something? I am using a voltage divider to get 4.5 V at the + input and a variable resistor varies the voltage at the - input. I was expecting the output to go high or low based on the variable input voltage.
