The ADuM1280/ADuM1281/ADuM1285/ADuM1286are dualchannel digital isolators based on the Analog Devices, Inc.,iCoupler®technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocoupler devices and other integrated couplers.With propagation delay at 23 ns, pulse width distortion is less than 2 ns for C grade. Channel-to-channel matching is tight at 5 ns for C grade. The two channels of the ADuM1280/ADuM1281/ ADuM1285/ADuM1286 are independent isolation channels and are available in two channel configurations with three different data rates up to 100 Mbps (see the Ordering Guide). Industrial grade models operate with the supply voltage on either side ranging from 3.135 V to 5.5 V and the automotive grades operate from 3.135 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. Unlike other optocoupler alternatives, the ADuM1280/ADuM1281/ ADuM1285/ADuM1286 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions. When power is first applied or is not yet applied to the input side, the ADuM1280 and ADuM1281 have a default high output, and the ADuM1285 and ADuM1286 have a default low output.For more information on safety and regulatory approvals, go towww.analog.com/iCouplersafety.ApplicationsGeneral-purpose multichannel isolationData converter isolationIndustrial field bus isolation​Hybrid electric vehicles, battery monitor, and motor drive
