ADuM1412 GENERAL DESCRIPTION The ADuM1410/ADuM1411/ADuM14121 are four- channel Digital Isolators based on Analog Devices , Inc., iCoupler technology. Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler Devices .

4 By avoiding the use of LEDs and photodiodes, iCoupler Devices remove the design difficulties commonly associated with opto-couplers. The usual concerns that arise with optocouplers, such as 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 one-sixth the power of optocou-plers at comparable signal data rates.

5 The ADuM1410/ADuM1411/ADuM1412 Isolators provide four independent isolation channels in a variety of channel configu-rations and data rates (see the Ordering Guide) up to 10 Mbps. All models operate with the supply voltage on either side ranging from V to V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. All products also have a default output control pin. This allows the user to define the logic state the outputs are to adopt in the absence of the input p ower.

6 Unlike other optocoupler alternatives, the ADuM1410/ADuM1411/ ADuM1412 Isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions. 1 Protected by Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.
