Comparators

Comparators

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.

Comparators with Integrated Reference

Analog Devices manufactures a range of application-specific comparator products, including –48 V telecom fuse monitors, bang-bang comparators, and window comparators.

High Speed Comparators (<100ns Propagation Delay)

Analog Devices high speed comparators feature <100 ns propagation delay and are a versatile and easy to use solution for a range of applications. Owing to our proprietary CB and XFCB fabrication processes, our comparators such as the AD790 possess a fast response time with outstanding input voltage resolution. Applications include: • High speed instrumentation • Clock and data signal restoration • Logic level shifting or translation • High speed line receivers • Threshold detection • Peak and zero-crossing detectors

Low Power Comparators

Analog Devices low power comparators provide a capable solution to demanding applications that must operate in the µA range. To cover a range of design needs, our low power comparators are available in commercial, industrial, and automotive temperature ranges, with feature such as noninverting inputs and inverting inputs. This portfolio supports applications such as Li-Ion monitoring, handheld instruments, LED/relay driving, control systems, and optoisolator driving.
