Analog Devices Inc. ADuM541x/ADuM641x Isolatoren

Die Analog Devices ADuM541x/ADuM641x Isolatoren sind 2,5/3,75kVrms digitale Vierkanal-Isolatoren mit integriertenisoPower® isolierten DC-DC-Wandlern. Diese DC-DC-Wandler sind mit iCoupler®-Technologie entwickelt und bieten eine einstellbare, isolierte Leistung von 3,15-5,25V. Diese Isolatoren verfügen über eine Gleichtaktsicherheit von 100kV/μs, 7ns Verzögerung und 150Mbps Datenrate für robuste Hochgeschwindigkeits-Datenübertragungen in lauten und rauen Umgebungen. Die ADuM541x/ADuM641x Isolatoren machen die Notwendigkeit für separate, isolierte DC-DC-Wandler bei der Entwicklung von isolierten Niedrigenergie-Anwendungen überflüssig. Die iCoupler-Chip-Scale-Transformator-Technologie der Geräte unterstützt isolierte logische Signale und die magnetischen Komponenten der DC-DC-Wandler. Erhältlich in einem kompakten, 24-poligen SSOP-Gehäuse, das Anwendern von ADuM541x/ADuM641x Isolatoren dabei hilft eine vollständige Isolationslösung mit einem kleinen Formfaktor zu entwickeln.

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.
