Inverting Op-Amp Resistor Calculator
For an inverting op-amp, the output voltage is given by:
\[
V_{out} = -\left(\frac{R_f}{R_{in}}\right)V_{in}
\]
To achieve a desired gain magnitude \(|A_v|\), use:
\[
|A_v| = \frac{R_f}{R_{in}} \quad \Rightarrow \quad R_f = |A_v| \times R_{in}
\]
* Enter the desired gain (magnitude) and the value of \(R_{in}\) (in ohms).
Step 1: Enter Parameters
Example: 10 (for a gain of -10)
Example: 1000 Ω (1 kΩ)
