The ADuM2210/ADuM22111 are 2-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 that are 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. 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 run at one-tenth to one-sixth the power of optocouplers at comparable signal data rates. The ADuM2210/ADuM2211 isolators provide two independent isolation channels in a variety of channel configurations and data rates （see the Ordering Guide）。 They operate with the supply voltage of either side ranging from 3.0 V to 5.5 V， providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. The ADuM2210W and ADuM2211W are automotive grade versions.
