The ADuM3154 is an SPIsolator™ digital isolator optimized for a serial peripheral interface (SPI) that includes support for up to four slave devices. Based on the Analog Devices, Inc., iCoupler® chip scale transformer technology, the low propagation delay and jitter in the CLK, MO/SI, MI/SO, and SS SPI bus signals support SPI clock rates of up to 17 MHz.The ADuM3154 isolator also provides a slave select multiplexing system that allows up to four slave devices to be serviced from one isolator. When a target slave is selected, the slave select signal propagates to the desired output with low propagation delay, allowing tight timing control. The isolated SSx is addressed through a 250 kbps low speed, 2-channel address bus, allowing the target slave device to be changed in as little as 2.5 μs.Applications Industrial programmable logic controllers (PLCs) Sensor isolation

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 ADuM1200 is a dual-channel, digital isolator with 2/0 directionality based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technologies, this isolation component provides 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.
