1. Operational Amplifiers

2. Operaional Amplifiers are used to amplify AC voltages as well as comparitors between two input voltages. An AC voltage was supplied by a function generator and the amplifed signal was graphed on the oscilliscope. The purpose of this lab was to demonstrate understanding of operational amplifers.

3. Materials and Methods:
Power supply
Op Amp LM741
100k ohm potentiometer
1M ohm potentiometer
Oscilliscope
Function Generator
5k resistor

Figure 5: Maximum amplification that could be achived using configuration from Task 4.


Figure 6: The voltage point that triggers change in the output was 3.2V.

5. Discussion

This lab demonstrated several configurations where Op Amps could be used. There were configurations that were non-optimal to show parameters that need to be met in order to use Op Amps corretly. Overall the experiments in this lab helped to solidify the characteristics of Op Amps.
