Working Principles

The MCP6547-E/P operates based on the principle of comparing two input voltages, IN+ and IN-, and providing 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 rail-to-rail input/output feature ensures accurate comparisons even when the input voltages are close to the supply rails.
