Voltage Gain Calculator

Formula

The formula to calculate the voltage gain of an op-amp in a non-inverting configuration is:

$\text{G} = 1 + \left(\frac{R_f}{R_{in}}\right)$

Where:

G is the voltage gain (V/V)
R_f is the feedback resistor (Ω)
R_in is the input resistor (Ω)

What is an Op Amp Gain?

An op amp gain refers to the amplification factor of an operational amplifier, which is a crucial component in analog electronic circuits. The gain determines how much the op amp will amplify the input signal. In a non-inverting amplifier configuration, the output voltage is in phase with the input voltage and is amplified by a factor determined by the resistors in the circuit.

Example Calculation

Example:

Feedback Resistor (R_f): 10 kΩ
Input Resistor (R_in): 2 kΩ

Step 1: Calculate the voltage gain:

$\text{G} = 1 + \left(\frac{10000}{2000}\right) = 1 + 5 = 6 \text{ V/V}$
