Key Features
- Quad op-amp operates from 3V to 32V single-supply or ±1.5V to ±16V dual supply, enabling flexible use in battery-powered and 5V-rail systems
- Common-mode input voltage range extends to the negative supply rail (ground in single-supply), allowing direct-coupled ground-referenced sensor signal amplification
- LM2902-compatible pinout in compact SOP-14 package facilitates drop-in replacement in existing designs with 1MHz gain-bandwidth product per amplifier
Applications
The NJM2902V-TE2 is used in low-cost signal conditioning circuits for industrial sensors, consumer electronics, and portable instruments where four independent op-amp channels are needed from a single 5V or 12V supply. It is well suited for audio pre-amplification, comparator-mode threshold detection, and active filter designs in applications where 1MHz bandwidth is sufficient and single-supply compatibility simplifies power architecture. Battery-operated instrumentation, white goods control boards, and automotive auxiliary circuits take advantage of its 3V to 32V supply range and ground-referenced input capability.

Frequently Asked Questions
Can the NJM2902V-TE2 amplify a 0V to 5V sensor signal directly from a single 5V rail without a negative supply?
Yes, the NJM2902V-TE2 is designed for single-supply operation from 3V to 32V with a common-mode input range that extends to the negative supply (0V / ground), allowing direct amplification of 0V to 5V sensor signals without a negative rail. The output can swing to within approximately 1V to 1.5V of the positive supply, so at 5V the output range is roughly 0V to 3.5V. For rail-to-rail output swing, a different op-amp family should be considered, but for standard sensor conditioning at 5V the NJM2902V-TE2 is fully adequate.
How many independent amplifier channels does NJM2902V-TE2 provide, and how does this reduce BOM count in a multi-channel filter design?
The NJM2902V-TE2 integrates 4 independent op-amp channels in a single SOP-14 package, replacing four discrete single op-amp ICs. In a 4-channel active low-pass filter design for an audio or sensor system, using one NJM2902V-TE2 reduces package count from 4 ICs to 1, cutting board area by up to 75% and reducing assembly costs. Each of the 4 channels has its own inputs and output, sharing only the power supply pins on the 14-pin SOP package.
At what signal frequency does the NJM2902V-TE2 provide unity gain, and what closed-loop bandwidth can be achieved at a gain of 10?
The NJM2902V-TE2 has a gain-bandwidth product of approximately 1MHz, meaning it achieves unity gain (0dB) at 1MHz. At a closed-loop gain of 10 (20dB), the -3dB bandwidth is approximately 100kHz (1MHz ÷ 10). This bandwidth is sufficient for audio signal processing up to 20kHz with a gain of 50, or for industrial sensor conditioning signals up to 100kHz with a gain of 10, making the NJM2902V-TE2 a practical choice for low-frequency analog front-end designs.
