In this configuration, the output is fed back to the negative or inverting input through a resistor (R2). The most basic circuit is the voltage buffer, as it does not require any external components.

Which pins of op amp IC 741 are used for offset nullification? The wiper arm of the potentiometer connects to the negative supply voltage. It consists of a 10-kilohm potentiometer connected between the offset null pins (1 and 5) of the op amp. Appendix 4 shows the recommended nulling circuit for an MC1741SC.
