Some or the other time we need to amplify DC and AC voltage. This Non inverting amplifier circuit can solve our purpose. It can amplify voltage to high extent. This project can be used anywhere where we need amplification of voltage.
The dependency of the output with the inverting and non-inverting pin can be simply explained as below,
If the inverting pin is high compared to other pin, the output is negative
If the non-inverting pin is high compared to other pin, the output is positive
This Non inverting amplifier circuit demonstrates the principle of working of opamp as non inverting amplifier. This project also uses the concept of negative feedback. The input voltage is given at positive pin of opamp while its negative pin is connected to resistors
R1 and R2. R1 is connected to ground and R2 is connected to Vout.
The amplification takes place according to the formula:
Amplification factor = [1+ (R1/R2)]
