ADuM1311 Industrial field bus isolation GENERAL DESCRIPTION 1 The ADuM1310/ADuM1311 are 3-channel digital isolators comparable signal data rates. The iCoupler also offers higher based on Analog Devices, Inc., iCoupler technology. Combin- channel densities and more options for channel directionality. ing high speed CMOS and monolithic air core transformer The ADuM1310/ADuM1311 isolators provide three technology, these isolation components provide outstanding independent isolation channels in a variety of channel performance characteristics superior to alternatives such as configurations and data rates up to 10 Mbps (see the Ordering optocoupler devices. Guide). All models operate with the supply voltage on either By avoiding the use of LEDs and photodiodes, iCoupler devices side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation remove the design difficulties commonly associated with opto- couplers. The typical optocoupler concerns regarding uncertain functionality across the isolation barrier. All products allow the current transfer ratios, maximum operating temperature, and user to predetermine the default output state in the absence of input lifetime effects are eliminated with the simple iCoupler digital VDD1 power with a simple control pin. Unlike other optocoupler interfaces and stable performance characteristics. The need for alternatives, the ADuM1310/ADuM1311 isolators have a patented external drivers and other discrete components is eliminated refresh feature that ensures dc correctness in the absence of input with these iCoupler products. Furthermore, iCoupler devices logic transitions and during power-up/ power-down conditions. consume one-tenth to one-sixth the power of optocouplers at 1 Protected by U.S. Patents 5,952,849 6,873,065 6,903,578 and 7,075,329.
