Working Principles

The TLC393CDG4 is a voltage comparator that compares two input voltages, IN+ and IN-, and produces an output voltage based on their relative magnitudes. It operates by amplifying the voltage difference between the inputs and driving the output either high or low depending on the comparison result. The rail-to-rail output swing allows the output voltage to reach close to the supply rails.
