The JRC 2902N (officially manufactured as the NJM2902N) is a quad single-supply operational amplifier known for its versatility in low-power and high-gain applications. It is part of the broader NJM2902 series produced by New Japan Radio (NJR), now under Nisshinbo Micro Devices.

Product Insights & Specifications

The NJM2902N is designed to operate from a single power supply across a wide voltage range, making it a standard choice for transducer amplifiers and DC gain blocks. Mouser

* Architecture: Quad Operational Amplifier (4 independent amplifiers in one IC).

* Operating Voltage: Wide range from 3V to 32V (Single) or ±1.5V to ±16V (Dual). Mouser

* Package Type: The "N" suffix denotes the DIP-14 (Dual In-line Package), which is widely used in through-hole PCB designs. Utsource

* Performance: Features a 100 dB voltage gain and a 0.5 MHz bandwidth, optimized for stability in single-supply systems without crossover distortion. Mouser

Market Trends & Availability

The market for the JRC 2902N remains stable due to its status as a "legacy standard" component in industrial and consumer electronics.

* Pricing: Wholesale prices on B2B platforms typically range from $0.24 to $0.53 per unit, depending on order volume and stock availability.

* Sourcing Trends: While New Japan Radio remains the primary manufacturer, the part is widely stocked by global distributors like Mouser and regional suppliers in Shenzhen. Mouser

* Demand: Steady demand continues in the maintenance and repair of legacy systems, as well as in budget-conscious DIY electronics and industrial sensor modules. Ic-Components

Strategic Comparison

In modern designs, engineers often evaluate the NJM2902N against other variants:

* NJM12902: A newer high-performance version capable of operating at lower voltages (2V) with triple the bandwidth (1.5 MHz). Nisshinbo-Microdevices

* Generic LM2902: The industry-standard equivalent from TI or ST. While functionally similar, the JRC version is often preferred in specific audio or Japanese-designed equipment for its consistent performance characteristics. Ti
