NJM2120D

Instrumentation, Op Amps, Buffer Amps Overview

The NJM2120D is a dual operational amplifier integrated with an analog switch, manufactured by Nisshinbo Micro Devices Inc. It utilizes bipolar technology and is housed in an 8-DIP package. The device operates within a supply voltage range of ±2.5V to ±18V. Key electrical characteristics include a typical slew rate of 2.2V/µs and a unity gain bandwidth of 7MHz. The input offset voltage typically measures 0.8mV, while the operating current ranges from 2.1mA to 6.0mA depending on the switch state.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrates dual operational amplifiers with a single analog switch function for combined signal processing and routing.
• Allows independent adjustment of gain for each amplifier channel (A or B).
• Capable of functioning as an analog switch at 0dB gain or as a Switch + Amp configuration.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific manufacturer datasheet version when sourcing this component. Confirm that the DIP-8 package matches the required PCB footprint. Ensure the design accommodates the specified absolute maximum ratings for supply voltage and power dissipation. Check for any obsolescence notices regarding the NJM2120 series before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the NJM2120D when a design requires both amplification and switching capabilities within a single package. It serves as a suitable alternative to separate op-amp and switch components. Consider its bipolar technology characteristics for audio and video applications requiring moderate bandwidth and slew rates.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the NJM2120 family, which includes variants like NJM2120M and NJM2120L. These devices share similar electrical characteristics but differ primarily in their packaging options, such as DMP8 and SIP8. The NJM2120D specifically denotes the dual in-line package variant designed for through-hole mounting.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The NJM4558 shares identical electrical characteristics with the amplifiers in the NJM2120. However, it lacks the integrated analog switch functionality. Verify if the switching requirement can be met by external components if substituting with the NJM4558.
