Working Principles

LMV393MMX operates based on the principle of voltage comparison. It compares the voltage levels at its two input pins (IN+ and IN-) and generates a digital output signal based on the result of this comparison. When the voltage at IN+ is higher than the voltage at IN-, the output goes high, indicating a positive comparison. Conversely, when the voltage at IN- is higher, the output goes low, indicating a negative comparison.
