Comparators and Op-Amps

Learn more about Microchip’s low power comparators and Op-amps that are designed to merge advantages of the PIC architecture and the flexibility of Flash program memory with the mixed signal nature of a voltage comparator. Together they form a low-cost hybrid digital/analog building block with the power and flexibility to work in an analog world. For more info on our comparators and Op-amps:
