Analog Devices Inc. ADuM541x/ADuM641x Isolators

Analog Devices ADuM541x/ADuM641x Isolators are 2.5/3.75kVrms quad-channel digital isolators with integrated isoPower® DC-to-DC converters. Developed using iCoupler® technology, the DC-to-DC converters offer adjustable isolated power from 3.15-5.25V. The isolators have a 100kV/μs common-mode transient immunity, 7ns delay, and 150Mbps data rate for robust, high-speed data transfer in noisy and harsh environments.

The ADuM541x/ADuM641x isolators eliminate the user's need for a separate, isolated DC-to-DC converter when designing low-power, isolated applications. The devices' iCoupler chip scale transformer technology supports isolated logic signals and the DC-to-DC converters' magnetic components. Available in a compact, 24-lead SSOP package, the ADuM541x/ADuM641x Isolators help users design a small-form factor, total isolation solution.

Design an Isolated pH Monitor with Temperature Compensation

Every industry handling liquids needs a measurement system for pH. It is important for wastewater systems and wastewater plants, but did you know that the water from a brewery needs to have a particular pH value before it reaches the sewage water system?
This article discusses the addition of high precision isolation to pH monitoring, essential when it is located far from the system, monitoring differing ground levels, or protecting a system from high voltage when an error occurs.
