Working Principles

The LM393APWR is a voltage comparator that compares the voltages at its two inputs, IN+ and IN-. The output, OUT, switches to a low state when the voltage at IN- is higher than the voltage at IN+. Conversely, the output switches to a high state when the voltage at IN+ is higher than the voltage at IN-. This behavior makes it useful for various applications such as level detection, signal conditioning, and waveform shaping.
