JRC

JRC (New Japan Radio) ICs in stock at YILUDA TECH. Five JRC lines are held as 100% original, new and unused material — audio op-amps, a stepper motor driver and a video signal processor.

What is available

Audio operational amplifiers — NJM4580M-TE2 in SOP-8, the dual op-amp widely used in audio paths, alongside NJM2068DD in DIP-8 and NJM8068G in SOP-8.
Motor control — NJM3771FM2 in PLCC-28, a dual stepper motor driver.
Video processing — NJM2529F in QFP-64, a TFT LCD video signal processor.

Why JRC parts get specified

The NJM audio op-amps are chosen for noise and distortion behaviour at low cost, and once a circuit is tuned around one the substitutes rarely measure the same. The stepper driver and video processor come from equipment built in the 2000s that is still in service — printers, plotters, small displays and audio gear.

Ordering notes

The same NJM device exists in DIP and SOP; the package is part of the code, so quote it in full.
For the motor driver, state the stepper current and supply voltage so the thermal margin can be checked.

Part numbers on hand

NJM4580M-TE2, NJM2068DD, NJM8068G, NJM3771FM2 and NJM2529F are in stock today.

Are the DIP parts original JRC?

Yes — 100% original, new and unused, with incoming inspection available on request.

Cross-reference notes

The NJM4580 and NJM2068 are both dual op-amps but are tuned differently — one for audio signal paths, the other for lower noise in instrumentation — so substituting one for the other changes the character of the circuit even when the pinout matches. For the stepper driver, the package and heatsinking determine how much current can be sustained, which is why the PLCC part is not simply a smaller version of a through-hole design.
