hi
im trying to perform a voltage comparator circuit using lm324n opamp
and got these test results at the point that opamp begins to reflect to inputs
#1: Vcc=5 V+=3.2 V-=4.2
#2: Vcc=5.7 V+=4.2 V-=5.7
#3 Vcc=5.6 V+=4 V-=5.7
why the opamp is so sensitive to Vcc
also this circuit was supposed to be a comparator so why would it respond to the input which is 1.5 volts lower than V-
