How to use this tool

  1. Enter first resistance, second resistance.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Gain = 1 + feedback resistance R2/ground resistance R1.

A WORKED EXAMPLE

Using first resistance = 100 Ω, second resistance = 200 Ω, the result is 3 ×. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind
