Digital Isolators

iCoupler® digital isolators combine ADI proprietary chip-scale micro-transformer technology, analog and mixed-signal circuits, as well as high-speed CMOS, creating devices with significant system level integration and functional advantages over other digital isolators and optocouplers. Offering isolation and innovation in one package, the iCoupler digital isolators portfolio is the broadest in the industry and includes standard digital isolators, digital isolators with isoPower, USB 2.0 compatible isolators, isolated gatedrivers, isolated I²C digital isolators, isolated RS-485 transceivers, isolated RS-232 devices, isolated ∑-∆ ADCs. With such a wide range of products, there is an iCoupler product to fit almost any application.
Medical – The ADuM4160 is a full/low speed USB isolator with a 5kV rms isolation rating and IEC-60601-1 safety approval. Learn more here on how the ADuM4160 can help ease your design time, increase space savings, and reduce solution costs.
Automotive – The ADuM120x, ADuM130x, and ADuM140x families of digital isolators have achieved AEC-Q100 automotive qualification and are also rated for under-the-hood operation up to 125°C. Learn more here on how these established families can be employed in your next automotive application.
