The ADuM240x1 are 4-channel digital isolators based on Analog DevicesR^ iCoupler(R) 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 photo diodes, i Coupler 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 i Coupler digital interfaces and stable performance characteristics. The need for external drivers and other discretes is eliminated with these i Coupler products. Furthermore, i Coupler devices run at one-tenth to one-sixth the power of optocouplers at comparable signal data rates. The ADuM240x isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). The ADuM240x models operate with the supply voltage of either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the ADuM240x provide low pulse width distortion (<2 ns for CRWZ grade) and tight channel-to-channel matching (<2 ns for CRWZ grade). Unlike other optocoupler alternatives, the ADuM240x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/powerdown conditions. 1 Protected by U.S. Patents 5,952,849 and 6,873,065.
