This document summarizes the simulation results of an operational amplifier component (NJM4741M) from its manufacturer's datasheet specifications. The simulations tested various electrical characteristics, including output voltage swing, input offset voltage, slew rate, input bias current, open loop gain, output short circuit current, and common mode rejection ratio. In each case, the simulation results closely matched the datasheet specifications, with most errors being less than 1%.
