The ADuM1280/ADuM1281/ADuM1285/ADuM1286 are dualchanneldigital isolators based on the Analog Devices, Inc.,iCoupler® technology. Combining high speed CMOS andmonolithic air core transformer technology, these isolationcomponents provide outstanding performance characteristicssuperior to alternatives, such as optocoupler devices and otherintegrated couplers.With propagation delay at 23 ns, pulse width distortion is lessthan 2 ns for C grade. Channel-to-channel matching is tight at5 ns for C grade. The two channels of the ADuM1280/ADuM1281/ADuM1285/ADuM1286 are independent isolation channelsand are available in two channel configurations with threedifferent data rates up to 100 Mbps (see the Ordering Guide).Industrial grade models operate with the supply voltage oneither side ranging from 3.135 V to 5.5 V and the automotivegrades operate from 3.135 V to 5.5 V, providing compatibilitywith lower voltage systems as well as enabling a voltagetranslation functionality across the isolation barrier. Unlikeother optocoupler alternatives, the ADuM1280/ADuM1281/ADuM1285/ADuM1286 isolators have a patented refreshfeature that ensures dc correctness in the absence of input logictransitions. When power is first applied or is not yet applied tothe input side, the ADuM1280 and ADuM1281 have a defaulthigh output, and the ADuM1285 and ADuM1286 have a defaultlow output.For more information on safety and regulatory approvals, go towww.analog.com/icouplersafety.Applications General-purpose multichannel isolation Data converter isolation Industrial field bus isolation Hybrid electric vehicles, battery monitor, and motor drive

The ADM2482E/ADM2487E are isolated data transceivers with ±15 kV ESD protection and are suitable for high speed, half-duplex or full-duplex communication on multipoint transmission lines. For half-duplex operation, the transmitter outputs and receiver inputs share the same transmission line. Transmitter Output Pin Y is linked externally to Receiver Input Pin A, and Transmitter Output Pin Z to Receiver Input Pin B. The parts are designed for balanced transmission lines and comply with TIA/EIA- 485-A-98 and ISO 8482:1987(E).The devices employ the Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package. An on-chip oscillator outputs a pair of square waveforms that drive an external transformer to provide isolated power. The logic side of the device can be powered with either a 5 V or a 3.3 V supply, and the bus side is powered with an isolated 3.3 V supply.The ADM2482E/ADM2487E driver has an active high enable, and the receiver has an active low enable. The driver output enters a high impedance state when the driver enable signal is low. The receiver output enters a high impedance state when the receiver enable signal is high.The device has current-limiting and thermal shutdown features to protect against output short circuits and situations where bus contention might cause excessive power dissipation. The part is fully specified over the industrial temperature range of −40°C to +85°C and is available in a 16-lead, wide-body SOIC package.Applications Isolated RS-485/RS-422 interfaces Industrial field networks Multipoint data transmission systems

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 simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler 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.APPLICATIONS General-purpose multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceivers Industrial field bus isolation Automotive systems
