Optional trimming of output offset voltage

WebThe point of the 741's (and others) offset null pins is to let you eliminate the DC bias caused by input offset. In production test, you ground the input to the op-amp circuit and monitor its output with a volt meter. You then trim the offset-null potentiometer until the circuit output is 0 V. The offset null is not intended to "add a voltage ... Webclosed-loop, the differential voltage is multiplied by the non-inverting closed-loop gain of the op amp, which is set by the circuit designer.
