The digital isolators reduce required PCB space as well as component cost and design complexity as multiple diodes and resistors are no longer needed.
Analog Devices has launched its intrinsically safe (IS) digital isolators based on IEC 60079-11:2011 standards. Analog Devices’ ADuM144x micropower 4-channel digital isolators based on proven iCoupler technology have enabled designers to implement isolation in designs ideally suited for applications such as industrial field instruments and for use in hazardous areas. When compared to traditional optocouplers, ADI’s IS-IS certified digital isolators simplify circuits by reducing required PCB board space along with component cost and design complexity as multiple diodes and resistors are no longer needed. These IS-IS digital isolators also provide higher data rates for more efficient operation and reduce installation cost over other protection methods.
With more than 1.8 billion channels shipped, these magnetically isolated products combine complementary metal oxide semiconductor (CMOS) and monolithic air core transformer technologies. ADI’s ADuM144x quad digital isolation devices are bundled in 16-lead QSOP (2.5kV) and 20-lead SSOP (3.75kV) footprints.
The devices received safety certifications from CSA-Sira and IECEx, global providers of testing and certification services.
