ADUM221N1BRWZ

ADUM221N is a dual-channel digital isolator based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, this isolation component provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The devices operate with the supply voltage on either side ranging from 1.8V to 5V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. It is widely used in application such as general-purpose multichannel isolation, industrial field bus isolation, automotive systems etc.
