Product review & video
welcome to electron line in this video we're going to talk about the instrumentation amplifier it is an amplification circuit that uses operational amplifiers in such a way that the output voltage is an amplification of a very small difference between two inputs in other words it applies small differences in the input signals and what is it used for for measuring such things as thermocouples or acquisition systems and things like that very small changes very small differences in the input will then have a very large output right here of course depending upon how big your gain is here's the equation that describes the output voltage relative to the difference of the two inputs and multiplied times is gain depends of course how you choose the values for your resistors now how do we come up with this equation right here well let me try to show you first of all we're going to define the out
