Make sure to power up the op-amp with ±15 V. (Use two DC voltage sources of the VDC type in PSpice.) Find vo when v1 = 2 V and v2 = −0.5 V. (Choose “Bias Point” for the analysis type in the simulation profile, enable the bias voltage display by clicking on the corresponding icon in the menu bar, and run the PSpice circuit.)
