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
LM741 Op-Amp IC Pin Diagram/Pinout
| Pin No | Pin Name | Description |
| 1,5 | OFFSET NULL | IC pins 1 & 5 are Offset null pins, these are used to eliminate the offset voltage and balance the input voltage. |
| 2 | INPUT- | This is the Inverting Input pin for Inverting signal Input. |
| 3 | INPUT+ | This is the Non-Inverting Input pin for Non-Inverting signal Input. |
| 4 | V- | Negative or Ground supply voltage |
| 6 | OUTPUT | The output pin of the op-amp IC |
| 7 | V+ | Positive Supply Voltage |
| 8 | NC | Not connected |
