Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific datasheet version and manufacturer documentation before integration, as component specifications may vary between revisions. Confirm that the 8-DMP package dimensions align with the target PCB footprint. Ensure the design accounts for potential oscillation risks when configuring the amplifier as a voltage follower, as noted in official application guidelines.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual J-FET input op-amp with a 5 MHz bandwidth and 20 V/µs slew rate is required in an 8-DMP package. Consider the NJM072B variant if improved stability is needed for voltage follower configurations, as the standard NJM072 series may exhibit oscillation in such applications. Verify power supply constraints against the ±4V to ±18V operating range.

Instrumentation, Op Amps, Buffer Amps Part Context

The NJM072M belongs to the NJM072/082 family of dual J-FET input operational amplifiers produced by Nisshinbo Micro Devices. This series is distinguished from the NJM072B/082B variants by enhanced AC features, including higher bandwidth and faster slew rates. The M suffix indicates the specific DMP8 surface-mount package configuration within the broader product lineup.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Official documentation recommends the NJM072B or NJM082B models for applications requiring greater stability in voltage follower configurations due to potential oscillation issues with the standard NJM072/082 series.

Instrumentation, Op Amps, Buffer Amps FAQ

Is the NJM072M stable in a voltage follower configuration?
