Working Principles

The MAX931CSA-T is a voltage comparator that compares the voltages at its non-inverting (IN+) and inverting (IN-) inputs. It operates by amplifying the voltage difference between the two inputs and providing a digital output based on the comparison result. When the voltage at the non-inverting input is higher than the voltage at the inverting input, the output goes high. Conversely, when the voltage at the inverting input is higher, the output goes low.
