GENERAL DESCRIPTION

The ADuM220x1 are 2-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.
