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

The ADuM130x are triple-channel digital isolators based on the Analog Devices, Inc.,iCoupler®technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocouplers.By avoiding the use of LEDs and photodiodes,iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simpleiCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with theseiCoupler products. Furthermore,iCoupler devices consume one-tenth to one-sixth of the power of optocouplers at comparable signal data rates.The ADuM130x isolators provide three independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide in the data sheet). Both models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the ADuM130x provide low pulse width distortion (<2 ns for CRW grade) and tight channel-to-channel matching (<2 ns for CRW grade). Unlike other optocoupler alternatives, the ADuM130x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and when power is not applied to one of the supplies.APPLICATIONSGeneral-purpose multichannel isolationSPI interface/data converter isolationRS-232/RS-422/RS-485 transceiversIndustrial field bus isolationAutomotive systems

The ADuM131x are 3-channel digital isolators based on 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.By avoiding the use of LEDs and photodiodes,iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, maximum operating temperature, and lifetime effects are eliminated with the simpleiCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with theseiCoupler products. Furthermore,iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates. TheiCoupler also offers higher channel densities and more options for channel directionality.The ADuM131x isolators provide three independent isolation channels in a variety of channel configurations and data rates up to 10 Mbps (see the Ordering Guide). All models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. All products allow the user to predetermine the default output state in the absence of input VDD1power with a simple control pin. Unlike other optocoupler alternatives, the ADuM131x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/ power-down conditions.APPLICATIONSGeneral-purpose multichannel isolationSPI interface/data converter isolationRS-232/RS-422/RS-485 transceiverIndustrial field bus isolation
