Combining high speed CMOS and monolithic transformer technology, these isolation components provide 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 char- acteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Further- more, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates. The ADuM3200/ADuM3201 isolators provide two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). They operate with 3.3 V or 5 V supply voltages on either side, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. The ADuM3200W and ADuM3201W are automotive grade versions qualified for 125°C operation. In comparison to the ADuM120x isolators, the ADuM3200/ ADuM3201 isolators contain various circuit and layout changes to provide increased capability relative to system-level IEC 61000-4-x testing (ESD, burst, and surge). The precise capability in these tests for either the ADuM120x or ADuM3200/ ADuM3201 products is strongly determined by the design and layout of the user’s board or module. For more information, see the AN-793 Application Note, ESD/Latch-Up Considerations with iCoupler Isolation Products. 1 Protected by U.S. Patents 5,952,849; 6,873,065; 7,075,329.
