The document summarizes the results of simulations and comparisons to datasheet specifications for an operational amplifier component. Key specifications tested include output voltage swing, input offset voltage, slew rate, input current, open-loop voltage gain versus frequency, and common-mode rejection ratio. The simulations were within 1-3% of datasheet values for most specifications tested.
