The ADuM32101 is a dual-channel, digital isolator based on Analog Devices, Inc., iCoupler technology. Combining high speed CMOS and monolithic transformer technology, this isolation component provides 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, 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 onesixth the power of optocouplers at comparable signal data rates. The ADuM3210 isolator provides two independent isolation channels. It operates 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. The ADuM3210 has a default output low characteristic in comparison to the ADuM3200/ADuM3201 models that have a default output high characteristic. The ADuM3210 is also available in 125C temperature grade.
