ADuM1281/ADuM1286 APPLICATIONS General-purpose multichannel isolation Data converter isolation Industrial field bus isolation Hybrid electric vehicles, battery monitor, and motor drive GENERAL DESCRIPTION The ADuM1280/ADuM1281/ADuM1285/ADuM12861 are dual- either side ranging from 3.135 V to 5.5 V and the automotive channel digital isolators based on the Analog Devices, Inc., grades operate from 3.135 V to 5.5 V, providing compatibility iCoupler® technology. Combining high speed CMOS and with lower voltage systems as well as enabling a voltage monolithic air core transformer technology, these isolation translation functionality across the isolation barrier. Unlike components provide outstanding performance characteristics other optocoupler alternatives, the ADuM1280/ADuM1281/ superior to alternatives, such as optocoupler devices and other ADuM1285/ADuM1286 isolators have a patented refresh integrated couplers. feature that ensures dc correctness in the absence of input logic transitions. When power is first applied or is not yet applied to With propagation delay at 23 ns, pulse width distortion is less the input side, the ADuM1280 and ADuM1281 have a default than 2 ns for C grade. Channel-to-channel matching is tight at high output, and the ADuM1285 and ADuM1286 have a default 5 ns for C grade. The two channels of the ADuM1280/ADuM1281/ low output. ADuM1285/ADuM1286 are independent isolation channels and are available in two channel configurations with three For more information on safety and regulatory approvals, go to different data rates up to 100 Mbps (see the Ordering Guide). www.analog.com/icouplersafety.
