NJM Series DIP-8 Operational Amplifier & ICs — NJM022D–NJM555D, 2pcs
A 2-piece pack of NJM (New Japan Radio / JRC) series DIP-8 operational amplifier and timer ICs, covering the NJM022D through NJM555D range. NJM series ICs are manufactured by New Japan Radio (NJR) and are widely used in audio equipment, signal processing, and general-purpose analogue circuit design. The NJM series is known for low noise, low distortion, and audio-grade performance, making these ICs popular in HIFI audio preamplifiers, equalizers, and signal conditioning circuits.

Typical Applications
- Audio Preamplifier: NJM op-amps in microphone preamplifier, phono stage, and line-level preamplifier circuits for HIFI audio equipment
- Signal Conditioning: Instrumentation amplifier and signal conditioning circuits for sensor signal amplification and filtering
- Active Filter: Low-pass, high-pass, and bandpass active filter design for audio crossover and signal processing applications
- Oscillator (NJM555D): Astable and monostable timer circuits using the NJM555D as a direct NE555 equivalent
- HIFI Upgrade: Replace standard op-amps in vintage audio equipment with NJM audio-grade equivalents for improved noise and distortion performance
FAQ
Q: Are NJM ICs compatible with standard op-amp pinouts?
A: Yes. NJM dual op-amps (NJM022D, NJM4558D, etc.) use the standard 8-pin dual op-amp pinout (same as LM358, TL072, NE5532) and are pin-compatible drop-in replacements in most circuits.
Q: Is the NJM555D compatible with the NE555?
A: Yes. The NJM555D is a direct pin-compatible equivalent of the NE555 timer IC with identical electrical characteristics.
