This document summarizes the results of simulations performed to model the operational characteristics of an NJM2162V operational amplifier manufactured by New Japan Radio. The simulations analyzed and compared the amplifier's output voltage swing, input offset voltage, slew rate, input bias current, open-loop voltage gain, and common-mode rejection ratio to the specifications listed in the manufacturer's datasheet. The simulation results were found to match the datasheet specifications within 2% error or less for all tested characteristics.
