Ideal Op-amp Gain Calculator

How to use Ideal Op-amp Gain Calculator

Inverting gain is−Rf/Rinput. Noninverting gain is1+Rf/Rground. Multiply by signed input voltage, then compare against your entered output bounds without clipping the model value.

1. Enter feedback resistor (ohms), input/ground resistor (ohms), input voltage (v), user minimum output bound (v), user maximum output bound (v).
2. Choose the stated convention and check the units and supported model.
3. Calculate, inspect the result, then copy or download it.

Good to know

• Positive resistances; finite ordered output bounds. Ideal linear feedback only, not actual rail/headroom, bandwidth, stability or part selection.
• Runs locally. Text/JSON fields are capped at30,000 characters; stricter page-specific and numeric-string limits also apply. Numeric inputs are bounded to magnitude1e15 and nonzero magnitude at least1e-100 unless an exact-string mode states otherwise. Approximate summaries use12 significant digits; CSV numeric cells retain the complete stored value and potentially formula-like string cells gain a protective apostrophe; unsupported, non-finite or detected underflow states return an error.
