inverting op amp gain calculator online

Use inverting op amp gain calculator online for feedback ohm, input ohm, signal V. Ideal virtual ground with negative gain. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter feedback ohm. Set input ohm, signal V. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
feedback ohmMain input. Positive values. 10000
input ohmOption. Positive values. 2000
signal VOption. Signed finite values. 0.2

Calculation method

gain = -feedback_ohm/input_ohm; ideal_output_V = -signal_V*feedback_ohm/input_ohm (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply inverting op amp gain calculator to the case below, keeping the displayed units and assumptions. Ideal virtual ground with negative gain.

Inverting Op Amp Gain Calculator — worked case

Settings: input ohm: 2000; signal V: 0.2

Input:

10000

Calculated result for these inputs:

Output:

{
  "gain": -5,
  "ideal_output_V": -1
}

Choose the right tool

Match the topology before entering values: series and parallel networks, inverting and noninverting stages, and buck and boost converters use different equations. Component ratings, parasitics, protection and measured conditions require separate review.

Limitations and common mistakes

  • Ideal virtual ground with negative gain. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
