The LM741 series are general purpose operational amplifiers which feature improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439, and 748 in most applications. The amplifiers offer many features which make their application nearly foolproof: overload protection on the input and output, no latch-up when the common-mode range is exceeded, as well as freedom from oscillators.

Brief Description

An LM741 operational amplifier is a DC-coupled high gain electronic voltage amplifier. It has only one op-amp inside. An operational amplifier IC is used as a comparator which compares the two signal, the inverting and non-inverting signal. The main function of this IC is to do mathematical operation in various circuits. Op-amps have large gain and usually used as Voltage Amplifier. The LM741 can operate with a single or dual power supply voltage.

OUTPUT Voltage = Gain * Input Voltage

Op-amp LM741 Pin Diagram

An op-amp can be used in two ways:

1. Inverting Op-amp

When input source is connected to inverting terminal PIN 2 and feedback with the output PIN 6 then the op-amp is in inverting condition. Like if PIN 2 is having +ve polarity then we will get –ve polarity of output from PIN 6.

GAIN = Rf/R1

Op-amp as inverting amplifier

 

2. Non-inverting Op-amp

When input source is connected to non-inverting terminal PIN 3 and PIN 2 is feedback with the output PIN 6 then the op-amp is in non-inverting condition. Like if PIN 3 is having +ve polarity then we will get +ve polarity of output from PIN 6.

GAIN = 1+ (Rf/R1)

Op-amp as non-inverting amplifier

 

Working Concept

When voltage at non-inverting input (+) is higher than the voltage at inverting input (-), then the output of comparator is HIGH. And if the voltage of inverting input (-) is Higher than non-inverting end (+), then output is LOW. The output of the operational amplifier is the product of the gain and the input voltage.

LM741 Applications

  • Comparators
  • DC Amplifiers
  • Integrator or Differentiators
  • Summing Amplifiers
  • Multi-vibrators
  • Active Filters
  • General feedback applications

 

2D-Model
