Working Principles

The LM6142BIN/NOPB operates as a voltage comparator by comparing the voltages at its inverting (IN-) and non-inverting (IN+) inputs. When the voltage at the IN+ input is higher than the voltage at the IN- input, the output goes high. Conversely, when the voltage at the IN- input is higher, the output goes low. This behavior allows the IC to compare voltages and provide a corresponding digital output.
