op amp gain bandwidth calculator online

Use op amp gain bandwidth estimate online for gbw Hz, closed loop gain. Single dominant-pole approximation using noise gain when appropriate. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter gbw Hz. Set closed loop gain. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
gbw HzMain input. Positive values. 1000000
closed loop gainOption. Positive values. 10

Calculation method

bandwidth_Hz = gbw_Hz/closed_loop_gain (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply op amp gain bandwidth estimate to the case below, keeping the displayed units and assumptions. Single dominant-pole approximation using noise gain when appropriate.

Op Amp Gain Bandwidth Estimate — worked case

Settings: closed loop gain: 10

Input:

1000000

Calculated result for these inputs:

Output:

{
  "bandwidth_Hz": 100000
}

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

  • Single dominant-pole approximation using noise gain when appropriate. 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.
