    Almost any type of op-amp capable of delivering 1-5 mA current can be used for this circuit. Most of any small transistors with maximum collector current handling around 100-200 mA can be used. The resistors R1 and R2 should be selected to supply the biasing point at 0.5Vcc, chose as high as possible but keep below 1/10 of op-amp’s input impedance.

        1 Resistor R2 and R3 form a voltage divider to provide a virtual ground for the op-amp at half the VCC voltage. (Note the equal values resistors). Capacitor C2 operates as a filter capacitor to keep the virtual ground node at a quiet level even if there are noise spikes and small disturbances on the VCC supply rail. Share
