What are the key features of NJM2902N?

Quad op-amp in DIP-14 through-hole package operating from a single 3 V to 32 V supply or dual ±1.5 V to ±16 V supply for versatile circuit design
85 dB common-mode rejection ratio (CMRR) with 0.5 µA max bias current enabling low-noise single-supply signal conditioning
Frequency-compensated voltage-feedback architecture with output voltage swing down to ground, compatible with single-supply comparator and amplifier topologies

What is NJM2902N used for?

The NJM2902N quad op-amp is widely used in single-supply signal conditioning circuits such as sensor amplifiers, active low-pass filters, and window comparators in consumer electronics, automotive accessories, and industrial control panels. Its ability to operate from 3 V to 32 V single supply makes it ideal for battery-powered instrumentation, 5 V microcontroller analog front ends, and automotive 12 V signal processing boards. The DIP-14 through-hole package suits prototype development, educational electronics kits, and repair of legacy through-hole equipment.

Frequently Asked Questions

What supply voltage range does the NJM2902N support, and can it run from a single 5 V microcontroller rail?

The NJM2902N supports a single supply from 3 V to 32 V or a dual supply of ±1.5 V to ±16 V. It operates correctly from a single 5 V rail, making it directly compatible with 5 V microcontroller systems without a negative supply. The output can swing to within a few hundred millivolts of ground on a 5 V single supply, which is suitable for most ADC input ranging and signal conditioning tasks.

How does the NJM2902N's 10 mV maximum input offset voltage limit its use in precision DC amplifier stages?

A 10 mV maximum input offset voltage on the NJM2902N means the amplifier adds up to 10 mV of DC error at its input. For a non-inverting amplifier with gain of 100, this introduces up to 1 V of DC offset at the output—unacceptable in precision DC signal chains where less than 10 mV total output offset is required. Engineers needing better DC accuracy should choose op-amps with 1 mV or lower offset, such as the LM2902 automotive-grade variant or a precision rail-to-rail device with 100 µV offset specification.

When is NJM2902N preferred over a single op-amp such as LM741 for a 4-channel comparator bank design?

The NJM2902N provides 4 independent op-amp channels in a single DIP-14 package, reducing component count by 4× compared to using 4 individual LM741 single op-amps each in DIP-8 packages. The NJM2902N also operates on a single 5 V supply versus the LM741 minimum ±5 V (±10 V total) dual supply, saving power supply complexity. For window comparator banks in battery-powered alarm systems or 4-channel analog monitoring circuits, the NJM2902N offers a more compact, lower-cost, and single-supply-compatible solution.
