The ADuM1410/ADuM1411/ADuM1412 are four-channel digital isolators based on Analog Devices, Inc., iCoupler The ADuM1410/ADuM1411/ADuM1412 isolators provide four technology. Combining high speed CMOS and monolithic air independent isolation channels in a variety of channel configu- core transformer technologies, these isolation components provide rations and data rates (see the Ordering Guide) up to 10 Mbps. outstanding performance characteristics superior to alternatives All models operate with the supply voltage on either side ranging such as optocoupler devices. from 2.7 V to 5.5 V, providing compatibility with lower voltage By avoiding the use of LEDs and photodiodes, iCoupler devices systems as well as enabling voltage translation functionality across remove the design difficulties commonly associated with opto- the isolation barrier. All products also have a default output control pin. This allows the user to define the logic state the couplers. The usual concerns that arise with optocouplers, such outputs are to adopt in the absence of the input power. Unlike as uncertain current transfer ratios, nonlinear transfer functions, other optocoupler alternatives, the ADuM1410/ADuM1411/ and temperature and lifetime effects, are eliminated with the simple ADuM1412 isolators have a patented refresh feature that ensures iCoupler digital interfaces and stable performance characteristics. dc correctness in the absence of input logic transitions and The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler during power-up/power-down conditions. 1 Protected by U.S. Patents 5,952,849 6,873,065 6,903,578 and 7,075,329. Rev.
