Op-Amp Voltage and Gain Calculator

?

Features:

  • Calculate gain and output voltage for both non-inverting and inverting op-amp circuits
  • Support for different units (Ω, kΩ, MΩ, V, mV)
  • View circuit diagrams for better understanding
  • Real-time calculation with mathematical formulas
  • Switch between non-inverting and inverting configurations

Instructions: Enter the resistor values, input voltage, and click Calculate to see the results.

Non-Inverting Op Amp Gain

non_inv_amp_cir_dia
\( V_{out} = A \cdot V_{input} \)
where \( A \) is the Gain
\( A = 1 + \frac{R_2}{R_1} \)

Inverting Op Amp Gain

inv_amp_cir_dia
\( V_{out} = A \cdot V_{input} \)
where \( A \) is the Gain
\( A = -\frac{R_2}{R_1} \)

For an inverting op-amp, the negative sign means the output voltage inverted compared to the input. Positive input results in a negative output, and negative input results in a positive output.
