I am trying to use UA741CP operational amplifier. To test it I wanted to create a buffer circuit in which input voltage would be equal to output voltage. I use 5 V DC as my supply rail. A voltage divider is used to reduce the input voltage of OpAmp (100k 1st, then 10k) which gives 0.45 V (V_in).
But when I measure V_out I get 1.82 V. Moreover, I can completely disconnect the non-inverting input (+) and it remains the same. Also I noticed that when I connect the OpAmp into the circuit the output voltage goes from around 1.8 V to 1.82 V in a couple of seconds.
Do you have an idea what I might be doing wrong?
