I connected one of the 4 opamp sections of the LM 324 in the buffer/unity follower configuration.
I noticed that for relatively low voltage levels the output of my buffer was in sympathy with the input. But as I started increasing the input ( I once connected the input directly to the 5v Vcc line) the output was stubbornly clamped at 3.81 volts, and increase in input wasn't reflected in output.
I tried the other opamp sections as well.
What could be the reason for this?
