Working Principles

The MCP6548T-I/SN is a precision voltage comparator that compares the voltage at its non-inverting input (VIN+) with the voltage at its inverting input (VIN-). It then produces a digital output signal based on this comparison. The comparator operates by amplifying the voltage difference between the inputs and driving the output to either a high or low state, depending on the result of the comparison.
