Noninverting Op-Amp

Noninverting Amplifier With T Feedback Network. Because of the high input impedance of the op amp, very small current flows through Rinv. The current through Rf and Rg are approximately equal. The voltage gain is (1 + Rf/Rg) similar to the simple noninverting amplifier configuration. This circuit is simply for comparison to the inverting amplifier with T feedback network and difference amplifier with T feedback network.
