This document summarizes the key specifications of an operational amplifier (opamp) with part number NJM1458 manufactured by New Japan Radio. It includes 3 sentences or less summaries of the opamp's output voltage swing, input offset voltage, slew rate, input current, open loop voltage gain vs. frequency, and common-mode rejection voltage gain as measured through simulation tests. The simulations show the opamp meets or exceeds its data sheet specifications for these key parameters.
