The JRC386 is an operational amplifier (op-amp) IC that was produced by New Japan Radio Co., Ltd. It is a dual operational amplifier that is designed for a wide range of applications, including audio amplification, filtering, and signal processing. The NJM386 has low noise and distortion, making it suitable for high-fidelity audio applications. Additionally, it is also known for its high output current and low power consumption, making it a popular choice for portable and battery-powered devices.

1. Amplification: The primary function of an op-amp is to amplify the voltage difference between its two input terminals (inverting and non-inverting). Op-amps can provide high gain, making them suitable for amplifying weak signals or performing signal conditioning.

2. Differential Inputs: Op-amps have two input terminals: the inverting (-) and non-inverting (+) inputs. The voltage difference between these inputs determines the amplifier’s output voltage.

An operational amplifier, often abbreviated as “op-amp,” is a versatile electronic component that is widely used in analog electronic circuits.
