Working Principles

LMV393M 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 the IN+ pin is higher than the voltage at the IN- pin, the output goes high (logic level 1). Conversely, when the voltage at the IN- pin is higher, the output goes low (logic level 0).
