Working Principles

The TLC393CPWR is a voltage comparator that compares two input voltages, IN+ and IN-, and produces a digital output signal based on their relative magnitudes. It operates by amplifying the voltage difference between the inputs and comparing it to a reference voltage (VREF). When the voltage at the non-inverting input (IN+) is higher than the voltage at the inverting input (IN-), the output (OUT) goes high. Conversely, when IN- is higher than IN+, the output goes low.
