4558D Datasheet – KA4558 – Dual Operational Amplifier

A dual operational amplifier, often referred to as a “dual op-amp,” is an integrated circuit (IC) package that contains two separate operational amplifiers. An operational amplifier (op-amp) is a versatile and widely used electronic component that amplifies the difference in voltage between two input terminals. Op-amps have a wide range of applications in electronics, including signal conditioning, amplification, filtering, voltage offset correction, and more.

4558D is Dual Operational Amplifier. The dual op-amp package conveniently provides two independent op-amps in a single IC, which can save space on a circuit board and simplify circuit design. Each op-amp within the package has its own set of inputs, output, and power supply pins, allowing you to use them separately for different tasks or in the same circuit for related operations.


• No frequency compensation required.

• No latch up.

• Large common mode and differential voltage range.

• Parameter tracking over temperature range.

• Gain and phase match between amplifiers.

• Internally frequency compensated.

• Low noise input transistors
