The 4558D is a monolithic integrated circuit designed for dual operational amplifier.

An operational amplifier, often abbreviated as op-amp, is an electronic component that amplifies the difference between two input voltages and produces an output voltage that is much larger than either input. It is widely used in electronic circuits for a variety of applications such as signal amplification, filtering, oscillation, and mathematical operations. The op-amp is a versatile building block for many analog and digital circuits and has become an essential component in modern electronics.
