A Single-Supply Op-Amp Circuit Collection
mil.ufl.eduA single-supply circuit (right side of Figure 1) connects the op-amp power pins to a positive voltage and ground. The positive voltage is connected to V CC+, and ground is connected to V CC-or GND. A virtual ground, halfway between the positive supply voltage and ground, is the reference for the input and output voltages.

ume.gatech.eduOp-amps that can handle those currents are rare and expensive. 2. If R = 10 Ωand VRef = 10 V R1 = 21-1*(10 Ω) = 10 Ω I1 = VRef/R1 = 10V/10 Ω= 1 A This current is more than a typical op-amp can handle.
