741 Pin Diagram. Below is the pinout diagram of a lm741 op amp chip. Page numbers for previous revisions may differ from page numbers in the current version.
3 82 typical application. Pin4 pin7 power supply. Inverting input this is where the positive part of the input signal that we want to amplify goes if we want our amplified signal.
In this circuit pin 3 non inverting terminal of op amp 741 is connected with the potentiometer and pin 2 inverting terminal is connected in between of r2 and rt1 thermistor which is making a voltage divider circuit.
Then the signal goes out of pin 6. Pin7 is the positive voltage supply terminal and pin4 is the negative voltage supply terminal. Where output from pin where output from pin 6 of ic2 is connected to the inverting input for negative feedback through. The voltage level between these pins can be in the range of 5.
