I can't nullify the output offset voltage of an LM741CN op amp.
I tried the circuit mentioned in the datasheet, but with no luck.
I connected the V- pin to ground of a 15V power supply and used a 10k pot as mentioned and the output is just stuck at +rail and doesn't even move a bit.
I also tried to use a 9V battery on a potentiometer to just compensate for the input offset voltage with the wiper end on the + pin. It worked and I got 30mv on the output but it also reads a 50 mA on the power supply and the op amp gets really hot.
I edited the circuit to bias the inputs to half of the supply voltage and made it my virtual ground now should be ok that the -v terminal is 7.5V below the inputs which allow for maximum swings on both sides like the circuit below. Are there any other cautions to take into account about this circuit? If there's any suggestions about any modifications or pitfalls in this circuit would be appreciated.
