Structural and Working Principle of NJM4558D

NJM4558D is a dual operational amplifier featuring two identical, high-performance amplifiers. The structure is built on a monolithic integrated circuit. The device has 8 pins, two for input and two for output. It also has a single power supply pin and a ground terminal. Each amplifier section of the device is composed of a differential amplifier and a common-mode feedback circuit. The output stage is designed using a push-pull complementary symmetrical output circuit. This increases the operational amplifier\'s power efficiency and reduces power supply demand.The differential amplifier is designed using transistors for input and current mirrors for output. This design helps increase the Operational Amplifier\'s input impedance and supply current capability. Common mode feedback is provided by two resistors which helps to maintain the output in symmetrical state even when the input signal polarity is reversed, thus preventing any DC drift.When comparing with other operational amplifiers, NJM4558D offers higher power efficiency, better power supply rejection, and lower noise. The output of each amplifier is stable and can be used as a standalone operational amplifier.
