Key Features
- Dual op-amp channels in a single SOP-8 package reduce component count by 50% versus discrete solutions
- High voltage supply range up to 36 V enables operation from automotive and industrial power rails without extra regulation
- Low power consumption extends battery life in portable sensor and signal-conditioning designs
- Wide input common-mode range including near-ground inputs simplifies single-supply circuit design
Applications
The NJM2147M dual op-amp is suited for active filter stages, signal amplification, and sensor interface circuits in industrial instrumentation and consumer electronics. Its wide supply voltage tolerance makes it a reliable choice for automotive sensor conditioning operating from 12 V rails. It also fits audio pre-amplifier and low-frequency oscillator designs where low quiescent current is a priority.

Frequently Asked Questions
What supply voltage range does the NJM2147M support for industrial and automotive designs?
The NJM2147M supports a supply voltage range up to 36 V on a single supply, or ±18 V on a dual supply. This wide range makes it compatible with 12 V automotive systems and 24 V industrial rails without additional voltage regulation, simplifying circuit design and reducing BOM cost in field instruments.
How does the NJM2147M perform in low-power battery-operated sensor applications?
The NJM2147M is designed for low quiescent current consumption, typically in the range of 500 µA per amplifier channel, which extends battery life in portable data loggers and wireless sensors. Its dual-channel architecture in an 8-pin SOP package saves board space while providing 2 independent amplifier stages per device.
What package does the NJM2147M use and how does it compare to a DIP-8 footprint for PCB layout?
The NJM2147M is housed in an SOP-8 (Small Outline Package) with 8 pins, occupying roughly 5 mm × 4 mm on the PCB—about 60% smaller than an equivalent DIP-8 footprint. This compact surface-mount profile suits high-density PCBs in handheld instruments and embedded control modules where through-hole components are impractical.
When should a designer choose the NJM2147M over a single-channel op-amp for an active filter design?
A designer should choose the NJM2147M when the circuit requires 2 filter stages, such as a 2nd-order Sallen-Key or Multiple Feedback filter, because both amplifier channels fit within a single 8-pin package. This integration eliminates one additional IC, reduces solder joints, and cuts PCB real estate by at least 30% compared to using two separate single op-amp packages.
