Working Principles

LMV339MT/NOPB works based on the principle of comparing two input voltages and providing a digital output based on the result of the comparison. Each comparator within the IC compares the voltage at its non-inverting input (IN+) with the voltage at its inverting input (IN-). If the voltage at IN+ is higher than the voltage at IN-, the output goes high (logic level 1), and if it is lower, the output goes low (logic level 0).
