GENERAL DESCRIPTION

The ADuM3400/ADuM3401/ADuM34021 are 4-channel digital isolators based on the Analog Devices, Inc., iCoupler? technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices.
