Working Principles

The MAX4928AETN+T is based on a differential amplifier configuration. It compares the voltage levels between the IN+ and IN- inputs and produces a digital output signal based on the comparison result. The comparator operates by amplifying the voltage difference between the inputs and comparing it to a reference voltage. If the voltage at the IN+ input is higher than the IN- input, the output switches to a logic high state; otherwise, it switches to a logic low state.
