“How can we compare two different voltage levels using an Op-Amp?”


Machines often have a multitude of sensors. And sometimes we would like to compare different values from these inputs to see which is larger. So how can we do this on the circuit itself? Well, we know that Op-Amps can handle two inputs at a time. And we also know that the type of values provided into the input will affect the output of the Op-Amp. So what if we were to use an Op-Amp that would output a voltage level to compare the two inputs? Well, this is known as an electronic comparator and is a fundamental of mechatronic systems.
