The ADUM2401 series quad-channel Digital Isolator based on Analog Devices, Inc., iCoupler? technology. Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics that are superior to alternatives, such as optocoupler devices. By avoiding the use of LEDs and photodiodes, iCoupler device removes 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 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. It provides four independent isolation channels in a variety of channel configurations and data rates.
