The ADuM2400 / ADuM2401 / ADuM2402 are 4-channel digital isolators based on Analog Devices, Inc., 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 opto-couplers. The 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. Furthermore, iCoupler devices run at one-tenth to one-sixth the power of optocouplers at comparable signal data rates.

The ADuM2400 / ADuM2401 / ADuM2402 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). The ADuM2400 / ADuM2401 / ADuM2402 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 ADuM2400 / ADuM2401 / ADuM2402 provide low pulse width distortion (<2 ns for CRWZ grade) and tight channel-to-channel matching (<2 ns for CRWZ grade). The ADuM2400 / ADuM2401 / ADuM2402 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions.
