In-Amp Common Mode Calculator
These tools calculate the common mode gain for instrumentation amplifiers using gain, differential voltage, and various other input parameters. It calculates both the internal node voltages and the output voltage of the part. It also calculates the resistor needed for a particular gain or the resulting gain using a certain resistor.
In-Amp Error Calculator
These tools will help estimate error contributions in your instrumentation amplifier circuit. It uses input parameters such as temperature, gain, voltage input, and source impedance to determine the errors that can contribute to your overall design.
