Working Principles

LMV393MM operates based on the principle of voltage comparison. It compares the voltage levels of the two input signals and generates a digital output based on the result. When the voltage at the non-inverting input (IN(+)) is higher than the voltage at the inverting input (IN(-)), the output goes high. Conversely, when the voltage at IN(-) is higher, the output goes low.
