Overview

The NJM4580D is a dual operational amplifier specifically designed for high-quality audio applications. It features a wide gain bandwidth of 15MHz and a slew rate of 5V/us, making it suitable for low-noise pre-amplification and signal processing. Its bipolar construction ensures low distortion and high output current capability.

Why Choose This Part

The NJM4580D offers a significant performance-to-cost ratio for audio designs, providing a low noise floor of 0.8 uVrms. Its wide operating voltage range from +/-2V to +/-18V allows for high headroom in analog signal paths. The classic 8-pin DIP package remains a favorite for through-hole prototyping and maintenance of vintage audio gear.

Applications

Audio Pre-amplifiers
Used in the input stages of mixers and recording equipment to boost low-level signals with minimal noise.
Active Filters
Ideal for high-fidelity equalizer circuits and crossover networks due to its 15MHz bandwidth.
Headphone Amplifiers
Capable of driving low-impedance loads in consumer and professional audio monitoring devices.
Industrial Control Signal Conditioning
Provides stable amplification for precision sensor interfaces operating within a +/-15V supply range.

Getting Started

To evaluate this part, use a standard breadboard or an 8-pin DIP socket for easy prototyping. Ensure that bypass capacitors (0.1uF ceramic) are placed as close to the V+ and V- pins as possible to maintain stability at its 15MHz bandwidth. Design for a maximum supply of +/-18V, though +/-15V is typical for most high-fidelity applications.
