ADI ADUM2200BRIZ

The ADuM2200/ADuM2201 are 2-channel digital isolators based on iCoupler technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics that are 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. 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 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 optocouplers at comparable signal data rates. The ADuM2200/ADuM2201 isolators provide two independent isolation channels in two channel configurations with data rates up to 10 Mbps. Both parts operate with the supply voltage on either side ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems, as well as enabling voltage translation functionality across the isolation barrier. The ADuM2200/ADuM2201 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions. Similar to the ADuM3200/ADuM3201 isolators, the ADuM2200/ ADuM2201 isolators contain various circuit and layout enhancements that provide increased capability relative to system-level IEC 61000-4-x testing (ESD, burst, and surge).
