# Instrumentation Amplifier Calculator

The Instrumentation Amplifier Calculator allows you to calculate the output voltage on instrumentation amplifiers by entering the voltage, resistor values and the resistor gain. You can print or email the results for later reference. Example figures have been entered to provide working calculations and example of how the formula is used to calculate the output voltage on Amp.
