Working Principles

The TLC551CDG4 is an analog comparator that compares two input voltages, IN+ and IN-, and produces a digital output based on their relative magnitudes. When the voltage at IN+ is higher than IN-, the output goes high, and when IN- is higher, the output goes low. The device operates with low power consumption and offers rail-to-rail input and output capabilities.
