Working Principles

The LMV7219M7 operates as a voltage comparator, comparing the voltages at its two input pins (IN(-) and IN(+)). When the voltage at IN(+) is higher than the voltage at IN(-), the output pin (OUT) switches to a high state. Conversely, when the voltage at IN(-) is higher, the output pin switches to a low state. This behavior allows the LMV7219M7 to determine the relationship between two input voltages accurately.
