Additional Details:

The NJM1303V is typically available in through-hole (DIP) and surface-mount (SOP) packages. Key specifications include a typical input offset voltage of a few millivolts, a high open-loop gain (typically in the thousands), and a slew rate suitable for audio frequencies. The amplifier's low input bias current and input offset current minimize errors in precision applications.
