The Schematic diagram of Astable Multivibrator is given below.Īs you can see from the above circuit of the square wave generator, the capacitor C and one resistor R are connected to inverting terminal of the operational amplifier. LM741 OP-AMP Pin diagram:īelow is the LM741 IC along with the pin diagram.Īs we discussed there are 4 input pins in green, and one output pin at pin6. Just as data, inside it is a very complex arrangement of resistors, capacitors and above all transistors, this arrangement is what allows all the magic and is encapsulated in a single circuit. And that is how the number 7-4-1 is formed.4 pins with the ability to receive an input signal.The number 741 means that the op amp consists of 7 functional pins.This amplifier was born in 1963, at the hands of Fairchild semiconductors, with the mission of making an “all-terrain” operational amplifier. The registration number of this integrated circuit is no coincidence: The LM741 is an integrated circuit corresponding to the series of operational amplifiers, which are designed for general purposes, since they are used as comparators, multi vibrators, or amplifiers. Due to its design, it has a high input impedance (Z) and a very low output impedance.

It is especially characterized by its response in: frequency, phase change and high gain that is determined by externally introduced feedback.
