The NJM4558, 4558D, NJM4559 integrated circuit is a dual high-gain operational amplifier internally compensated and constructed on a single silicon chip using an advanced epitaxial process.
The 4558D is a dual operational amplifier (Op-Amp) integrated circuit manufactured by New Japan Radio Co., Ltd. It is a high-performance, low-noise, and wide bandwidth operational amplifier with a high slew rate and low power consumption. It is commonly used in a variety of analog circuits such as audio amplifiers, filters, and oscillators.
Combining the features of the NJM741 with the close parameter matching and tracking of a dual device on a monolithic chip results in unique performance characteristics. Excellent channel separation allow the use of the dual device in single NJM741 operational amplifier applications providing density.
It is especially well suited for applications in differential-in, differential-out as well as in potentiometric amplifiers and where gain and phase matched channels are mandatory.
What is Dual Operational Amplifier?
A dual operational amplifier is a type of integrated circuit that contains two independent operational amplifiers within a single package.
Each op-amp in a dual operational amplifier typically includes a differential input stage, a gain stage, and an output stage. The input stage amplifies the difference between the two input signals, while the gain stage amplifies the signal to the desired level. The output stage provides a low impedance output signal that can drive a load or be further processed by other circuit elements.
