Op-Amp Voltage Gain Calculation
- In a non-inverting op-amp configuration, the voltage gain is determined by the ratio of the resistances in the feedback network.
- The voltage gain (AV) of a non-inverting op-amp is given by the formula:
- AV = 1 + (Rf / Rin), where Rf is the feedback resistance and Rin is the resistance between the input and the inverting terminal.
Given:
- Feedback resistance, Rf = 20 kΩ
- Resistance between input and inverting terminal, Rin = 4 kΩ
Using the formula for the voltage gain of a non-inverting op-amp:
AV = 1 + (Rf / Rin)
Substitute the given values:
AV = 1 + (20 kΩ / 4 kΩ)
AV = 1 + 5
AV = 6
Therefore, the value of the voltage gain is 6. Thus, the correct option is 6
