Description and Introduction

ULTRA WIDE BAND, HIGH SLEW RATE QUAD OPERATIONAL AMPLIFIER The **NJM2138M** is a high-performance dual operational amplifier (op-amp) designed for precision analog signal processing applications. Manufactured by New Japan Radio (NJR), this IC features low noise, low distortion, and wide bandwidth, making it suitable for audio equipment, instrumentation, and communication systems.  

Key specifications include a low input noise voltage of 3.5nV/√Hz, a high slew rate of 10V/µs, and a gain bandwidth product of 15MHz. The NJM2138M operates over a wide supply voltage range (±2V to ±18V), ensuring flexibility in various circuit designs. Its built-in phase compensation enhances stability, while the short-circuit protection improves reliability in demanding environments.  

The device is housed in a compact **8-pin DIP or SOP package**, facilitating easy integration into both prototyping and production boards. Its excellent DC characteristics, such as low input offset voltage and high common-mode rejection ratio (CMRR), make it ideal for precision amplification tasks.  

Engineers often select the NJM2138M for high-fidelity audio applications, active filters, and sensor signal conditioning due to its balanced performance and robust design. Its combination of low noise and high-speed operation ensures clean signal amplification, making it a dependable choice for professional-grade electronic systems.
