noninverting op amp gain calculator online

Use noninverting op amp gain calculator online for feedback ohm, ground ohm, input V. Ideal linear amplifier; rail limits and bandwidth excluded. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter feedback ohm. Set ground ohm, input 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
ground ohmOption. Positive values. 1000
input VOption. Signed finite values. 0.1

Calculation method

gain = 1+feedback_ohm/ground_ohm; ideal_output_V = input_V*(1+feedback_ohm/ground_ohm) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply noninverting op amp gain calculator to the case below, keeping the displayed units and assumptions. Ideal linear amplifier; rail limits and bandwidth excluded.

Noninverting Op Amp Gain Calculator — worked case

Settings: ground ohm: 1000; input V: 0.1

Input:

10000

Calculated result for these inputs:

Output:

{
  "gain": 11,
  "ideal_output_V": 1.1
}

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 linear amplifier; rail limits and bandwidth excluded. 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.
