The ADuM141x1 are four-channel digital isolators based on Analog Devices, Inc. iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technologies, these isolaTIon components provide outstanding performance characterisTIcs 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 usual concerns that arise with optocouplers, such as 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.
