NJM4556AD
Overview
The NJM4556AD is a high-output current dual operational amplifier designed by New Japan Radio to drive low-impedance loads that standard op-amps cannot handle. It can deliver up to 70mA of output current, making it a staple for headphone amplification and line-driving applications. Operating on a wide supply range from +/-2V to +/-18V, it offers a 3V/us slew rate and 10nV/rtHz noise performance in a standard DIP8 package.
Why Choose This Part
The primary advantage is its high output current capability of 70mA, which allows it to maintain signal integrity into difficult loads. It combines this power with low noise and a wide operating voltage range, making it a versatile choice for analog signal processing where standard dual op-amps lack sufficient drive strength.
Applications
Key Specifications
Getting Started
As a standard DIP8 bipolar op-amp, the NJM4556AD can be prototyped easily on a breadboard or perfboard. Ensure adequate decoupling capacitors (typically 0.1uF ceramic) are placed close to the V+ and V- pins to maintain stability during high current transients. Refer to the New Japan Radio datasheet for thermal considerations when driving maximum loads continuously.
