LM741 Pinout Connections
In this article, we will explain the LM741 Pinout Connections.
A LM741 is a 8-pin op amp, meaning it has 8 pins all having their different functions.
Below is the pinout diagram of a LM741 Op amp chip:
Pin 1: Offset Null- This is the pin where we add voltage to if we want to eliminate the offset voltage.
This is if we want to completely balance the input
voltages. More on this at offset terminals
Pin 2: Inverting Input- This is where the positive part of the input signal that we want to
amplify goes if we want our amplified signal inverted. If we don't want it inverted, we place the positve
part of the signal into the Non-inverting terminal and place the negative or ground part of our signal
here.
Pin 3: Non-inverting Input- This is where the positive part of the input signal that we want
amplified goes if we want our signal non-inverted.
Pin 4: V-- The LM741 Op amp is a dual power supply op amp, meaning it must be supplied positive
DC voltage and negative DC voltage. Pin 4 is where the op amp gets supplied with negative DC voltage.
Pin 5: Offset Null- This is the pin where we add voltage to if we want to eliminate the offset voltage.
This is if we want to completely balance the input
voltages. More on this at offset terminals
Pin 6: Output- This is the terminal where the output, the amplified signal, comes out of. Whatever
output the amplifier will drive gets connected to this terminal.
Pin 7: V+- This is the terminal which receives the positive DC voltage.
Pin 8: NC- This pin stands for Not Connected. It is not used for anything and should be left open.
