iCoupler Digital Isolator ICs for Electric-Hybrid Automotive - ADuM120xW, ADuM130xW and ADuM140xW - Analog Devices

Analog Devices (ADI) has announced the availability of company’s new iCoupler products, the ADuM120xW, ADuM130xW and ADuM140xW digital isolators.  The new iCoupler digital isolator devices are designed for electric-hybrid automotive systems, and have achieved AEC-Q100 automotive qualification, a critical stress test qualification for automotive ICs (integrated circuits) delivered by AEC (Automotive Electronics Council).

Analog Devices’ ADuM120xW, ADuM130xW and ADuM140xW iCoupler Digital Isolator ICs

The ADuM120xW (2-channels), ADuM130xW (3-channels) and ADuM140xW (4-channels) digital isolators are based on ADI’s iCoupler chip-scale micro-transformer technology. iCoupler digital isolators are relatively insensitive to temperature and offers long-term reliability. Because iCoupler products have a digital interface, there is no need for external signal conditioning components, and they consume one-tenth to one-sixth the power of opto-couplers at comparable signal data rates. The CMOS-based parts operate with the supply voltage on either side ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation across the isolation barrier.
