EXPERIMENT#1: OP-AMP as an Inverting Amplifier
Implement the circuit of an inverting amplifier for a gain of 10. The input to this circuit should be
a sinewave of 1 V peak to peak and 100 Hz frequency. Display the waveforms you obtain
separately for the input and output. Select the appropriate thickness of the waveforms so that the
examiner can evaluate the results you get.

PROCEDURE:
Circuit Assembly:
1. Connect the positive terminal of your dual DC power supply (e.g. +12V) to pin 7 of the
IC741.
2. Connect the negative terminal of your dual DC power supply (e.g. -12V) to pin 4 of the
IC741.
3. Connect the common ground of the DC power supply to a designated ground rail on your
breadboard. This will serve as your circuit's ground reference.
4. Connect one end of the input resistor (R1) to pin 2 of the IC741.
5. The other end of R1 will be connected to the function generator's output.
6. Connect one end of the feedback resistor (R2) to pin 6 of the IC741.
7. Connect the other end of R2 to pin 2 of the IC741, sharing the connection point with R1.
8. Connect pin 3 of the IC741 directly to the common ground rail on your breadboard.
9. Connect the positive output terminal of the function generator to the free end of R1.
10. Connect the ground terminal of the function generator to the common ground rail on your
breadboard.
