First terminal of the optional input-offset trim network.
Leave open in the illustrated circuit.
Use TI’s trim network only when needed; its other end is pin 8.
Negative-feedback summing node.
Connect the 90 kΩ/10 kΩ resistor junction.
Positive signal input.
Apply 0.20 V relative to the 0 V supply midpoint.
Negative power rail.
Connect −15 V; bypass locally to 0 V with 100 nF.
Not signal ground in this circuit.
No electrical connection is specified for this pin.
Leave unconnected.
Amplifier output and feedback source.
Connect 90 kΩ to IN− 2 and a high-impedance output meter.
Positive power rail.
Connect +15 V; bypass locally to 0 V with 100 nF.
Second terminal of the optional input-offset trim network.
Leave open in the illustrated circuit.
Paired with pin 1; this is not the LM741 null-pin arrangement.
