Working Principles

LM393AMX works based on the principle of voltage comparison. It compares the voltages applied to its two input pins (IN+ and IN-) and produces a digital output based on the result of the comparison. If the voltage at IN+ is higher than the voltage at IN-, the output goes low (logic 0). Conversely, if the voltage at IN- is higher, the output goes high (logic 1).
