Introduction to LM4558

Hi, friends welcome to the new post. We will discuss Introduction to LM4558. It is a monolithic IC circuit that is used for dual operational amplifier applications. It is preferred for volts followers circuits since its features like common-mode input volts and the non-existence of a latch-up maker.

This module is protected from the short circuit and inner frequency compensation that makes sure stability in the absence of outer elements. Here we will cover its different functions working and some other points. That is described here so let get started Introduction to LM4558.

Introduction to LM4558

• The LM4558 IC comprises of two operational amplifiers and is used for amplification circuits. its basic functions are comparator, differential amplifiers, and mathematical operations like addition subtraction.

• It is the option of a fine for voltage follower circuits due to the existence of a high-value common-mode input volts range and not the existence of latch-up.
• Its best feature is that it can be used in two different applications due to the existence of two operational amplifiers

Working of LM4558 IC

The inner circuit of LM4558 IC with two operational amplifiers is seen in below figure as A.

• The two operational amplifiers for operational amplifiers are circuits such as comparators, differential amplification, and mathematical operations.
• Here we use operational amplifiers to make a simple comparator circuit for understanding the operation of operational amplifiers.
• In the second diagram, we use one operational amplifier for making the circuit.

• There is a comparison made with voltage V1 and V2, and the output is Vo. The VCC supplies power to the circuit.

 Vid = V1 – V2

If Vid > 0, then Vo = VCC.

If Vid < 0, Vo = 0V or GND

According to conditions of output, we can find Vid is positive or negative and also V1 is high or V2 is higher at input. With high voltage, the output of the function of the operations amplifier can be seen.
