Working Principles

LMV393IDRG4 operates based on the principle of voltage comparison. It compares the voltages applied to its two input pins and generates a digital output based on the result of the comparison. 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 than IN+, the output goes low.
