Hello friends, I hope you all are doing great. Today, I am going to share the new INA128 Instrumentation Amplifier Library for Proteus Simulation , the fifth of the lab ICs in our University Lab series. If you have looked for a Proteus simulation of an instrumentation amplifier, this is it. Strain gauges, load cells, pressure sensors, thermocouples and ECG electrodes all give tiny signals, a few millivolts or less, sitting on top of a much larger common voltage. An ordinary op-amp circuit struggles with that. An instrumentation amplifier is built for it, and the INA128 is the one most university labs use.
