Hello friends! Welcome back to ElectroDuino. This blog is base on the  741 Op-Amp IC. Here we will discuss the Introduction to 741 Op-Amp IC, Pin Diagram/Pinout, Specifications, Features, LM741 IC Equivalent IC, and its applications. 

Introduction

The 741 Op-Amp or operational amplifier is a DC-coupled high gain differential amplifier with external negative feedback. It consists of 8 pins and It has only one op-amp inside. The main function of the 741 Op-Amp IC is to do the mathematical operations in various circuits. The LM741 Op-Amp IC can operate with a single or dual power supply voltage. 

OUTPUT Voltage = Gain * Input Voltage
