Hi all!
I am new in op amp, and currently studying the basics of it..
So I designed this LM741 circuit with a single supply, I made the input at the V+ to be 1.5v supplied by a voltage divider, and a gain of 3 with feedback resistor being 20k and R1 being 10k.
My problem is, according to the op amp rule, V will try to be the same as V+, but in my case, it is about 0.35v different.
Also the V out I calculated with the gain is suppose to be 4.5v, but it measured a 5.5v.
Am I doing anything wrong?
Any help would be so appreciated guys!
Thanks in advance!!
Ps: I've tried searching in the thread for any related post but I couldn't find.
