Hello and please help!
I am trying to make an amplifier with a basic op amp and so far no luck.
I need a 1.2 gain for an input signal that ranges 0-10V. The output should be 0-12V and max 350mA needed.
I tried using a 741 OP AMP with a voltage divider (with a 1k and 5k resistor) and the output wont go above 0.3V I even flipped the resistors to get a different "division" and the output didnt change. Any ideas or components that I may be missing ?
I think that to get the desired current I'll use an NPN transistor. But first things first, I should get my signals working... :/
Thanks ahead of time
