What is JRC4558 

The JRC4558 is a dual operational amplifier integrated circuit (IC) manufactured by Japan Radio Corporation (JRC), now part of New Japan Radio (NJR). It's a versatile component used in various electronic applications, particularly popular in guitar pedals and audio circuits.

Known for its robust performance, it offers strong input impedance, substantial voltage amplification (with a gain of up to 100dB), and operates within a wide power supply range (from ±4V to 18V). This IC contains two separate op-amps within its 8-pin package and is available in different formats such as DIP (Dual Inline Package) and SOP (Small Outline Package). Its flexibility and reliability have made it a favorite among engineers, hobbyists, and musicians for decades.

1. Where to Use JRC4558 

The JRC4558 op-amp is versatile, useful in general applications like comparisons, amplification, and math operations. It's designed for transducer amplification and simplifying DC blocks in single-supply voltage systems. Operating directly from a 5V source, it's popular for its dual-op-amp setup, offering cost-effectiveness and strong performance, appealing to hobbyists and engineers.

4. How to Use JRC4558 Op-Amp?

The JRC4558 op-amp is widely applied in general operations like amplification, differentiation, and various mathematical and comparator circuits. Specifically designed for single-voltage systems, transducers, DC amplification blocks, and diverse analog circuits.

In this circuit using the JRC4558 as a differential amplifier, the goal is to convert a single-ended input voltage ranging from 2V to 10V into a ±8V differential output voltage, operating with a 15V supply voltage and a 12V reference voltage. The design intentionally limits the output to maximize linearity.

This configuration comprises two amplifiers: the first acts as a buffer amplifier (Vout+), while the second inverts the input voltage and combines it with the 12V reference to produce the Vout- signal. Both Vout+ and Vout- output voltages range between 2V to 10V. The difference between Vout+ and Vout- results in the differential output voltage, Vdiff.
