DescriptionThe ADuM3210 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 charac-teristics 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 charac-teristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler ADuM3210 devices consume one-tenth to one- sixth 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 125°C temperature grade.
In comparison to the ADuM1210 isolator, the ADuM3210 isolator contains various circuit and layout changes providing increased capability relative to system-level IEC 61000-4-x testing (ESD, burst, and surge). The precise capability in these tests for either the ADuM1210 or ADuM3210 products is strongly determined by the design and layout of the user's board or module.
