ADuM2402 APPLICATIONS General-purpose, high voltage, multichannel isolation ture and lifetime effects are eliminated with the simple iCoupler Medical equipment digital interfaces and stable performance characteristics. Further- Motor drives more, iCoupler devices run at one-tenth to one-sixth the power Power supplies of optocouplers at comparable signal data rates. GENERAL DESCRIPTION The ADuM2400/ADuM2401/ADuM2402 isolators provide four 1 independent isolation channels in a variety of channel configura- The ADuM2400/ADuM2401/ADuM2402 are 4-channel digital tions and data rates (see the Ordering Guide). The ADuM2400/ isolators based on Analog Devices, Inc., iCoupler technology. ADuM2401/ADuM2402 models operate with the supply voltage Combining high speed CMOS and monolithic air core transformer of either side ranging from 2.7 V to 5.5 V, providing compatibil- technology, these isolation components provide outstanding ity with lower voltage systems as well as enabling a voltage performance characteristics that are superior to alternatives, such translation functionality across the isolation barrier. In addition, as optocoupler devices. the ADuM2400/ADuM2401/ADuM2402 provide low pulse By avoiding the use of LEDs and photodiodes, iCoupler devices width distortion (<2 ns for CRWZ grade) and tight channel-to- remove the design difficulties commonly associated with opto- channel matching (<2 ns for CRWZ grade). The ADuM2400/ couplers. The typical optocoupler concerns regarding uncertain ADuM2401/ADuM2402 isolators have a patented refresh feature current transfer ratios, nonlinear transfer functions, and tempera that ensures dc correctness in the absence of input logic transitions 1 and during power-up/power-down conditions.
