Diagrams of the IC are shown below – OPAMP LM 741 PINOUT Op Amp LM 741 PINOUT OPAMP LM358 IC PINOUT OpAmp LM358 IC OPAMP WORKING To avoid noise signals we connect a variable resistor (POT-Potentiometer) in between +Offset and –Offset.

In op-amp LM741 Offset is used because any sensor can give output without any input. Difference between LM358 & LM741 is, LM358 is newer and have two OP-AMP on chip while in 741 only one OP-AMP is present. Two commonly used opamp are LM741 & LM358. In simple terms, sensors give a low voltage output that cannot be easy to read, so an operational amplifier is used to amplify the signal. Operational amplifier is a DC coupled high gain voltage amplifier with a differential input and whose output is several hundreds of times of its differential input.

Large common-mode rejection ratio (CMRR) and differential voltage ranges.In this tutorial section we will discuss about input and output signals of operational amplifier or OPAMP and OPAMP ICs which includes LM741 and LM358.

TO-99 and CDIP – 300 ˚C (for 10 seconds – prescribed).

PDIP package – 260 ˚C (for 10 seconds – prescribed).

This is the Non-Inverting Input pin for Non-Inverting signal Input. This is the Inverting Input pin for Inverting signal Input. IC pins 1 & 5 are Offset null pins, these are used to eliminate the offset voltage and balance the input voltage. OUTPUT Voltage = Gain * Input Voltage LM741 Op-Amp IC Pin Diagram/Pinout LM741 Op-Amp IC Pin diagram/ Pinout Pin No The LM741 Op-Amp IC can operate with a single or dual power supply voltage.

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