This document provides a device modeling report for an operational amplifier (opamp) component. It includes specifications for the opamp such as output voltage swing, input offset voltage, slew rate, input current, voltage gain, and common mode rejection ratio. Simulation results are presented and compared to data sheet specifications to evaluate the accuracy of the developed SPICE model.
