A comparator is used to compare a measurable quantity with a reference or standard such as two voltages or currents. It outputs a digital signal showing the results. Analog Devices offers an extensive portfolio of high speed and low power comparators and this allows us to provide our customers with more complete signal chain solutions. Our comparator offerings range from the fastest Si-based comparator on the market today to very low power CMOS comparators that consume only microamperes of power. Find the right comparators for your application with our selection tool and design tool.
