Working Principle of JRC4558

The JRC4558 operates by amplifying the voltage difference between its inverting and non-inverting inputs. Each op-amp inside the IC works independently while sharing the same power supply rails. External resistors and capacitors determine how each amplifier behaves, allowing it to function as a preamplifier, active filter, buffer, integrator, or differential amplifier. The IC provides stable performance, low noise, and minimal distortion, which is why it is highly preferred in audio circuitry.
