Working Principles

The LP2901DE4 compares two input voltages, IN+ and IN-, and produces an output voltage based on their relationship. When the voltage at IN+ is higher than IN-, the output goes high, and when IN- is higher, the output goes low. The comparator operates using a differential amplifier configuration, which amplifies the voltage difference between the inputs.
