NJM064M

Instrumentation, Op Amps, Buffer Amps Overview

The NJM064M is a quad J-FET input operational amplifier designed as a low-power variant of the NJM082. It features high input impedance, wide bandwidth, and high slew rate with low input offset and bias current. The device operates on supply voltages from ±2V to ±18V. Key electrical characteristics include a unity gain bandwidth of 1MHz, a slew rate of 3.5V/µs, an operating current of 200µA per circuit, and an input resistance of 10^12Ω. It utilizes bipolar technology within a monolithic integrated circuit.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type and ordering suffix against official Nisshinbo Micro Devices documentation before procurement. Confirm availability status as distribution channels may vary. Ensure the selected component matches the required pin configuration and thermal specifications for the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad channel configuration is required alongside J-FET input characteristics. Compare against dual-channel alternatives like the NJM062 if fewer channels suffice. Consider the ±2V to ±18V supply range and 1MHz bandwidth limits relative to system requirements. Verify compatibility with existing PCB footprints for the DIP8 or DMP8 packages.

Instrumentation, Op Amps, Buffer Amps Part Context

The NJM064M belongs to the NJM062/064 series of J-FET input operational amplifiers manufactured by Nisshinbo Micro Devices. This series serves as a low-power alternative to the NJM082 family. The NJM064 specifically provides four independent amplifier channels in a single package, sharing terminal assignments with other industry-standard quad op-amps such as the NJM2902 and NJM3403.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible replacements include the NJM062 (dual channel version) and legacy equivalents sharing identical pinouts such as the NJM2902, NJM3403, NJM2058, NJM2059, and NJM2060.
