I'm working on a project in which I have to use an op amp in a single supply configuration. I understand that in order to get this to work, I have to ground the negative supply rail AND connect the + input terminal to 1/2 the supply voltage. I know that I have to do this in order to get the circuit to work. My question is why?
I understand that when I ground the negative supply, the output can only swing between (theoretically) 0v and the voltage of the positive supply.
I'm having trouble understanding what applying half the supply voltage to the non-inverting terminal does.
If someone could provide a thorough explanation I will be most grateful.
Thank You
