ADUM1281ARZ-RL7

ADuM1281 is a 3KV RMS dual channel digital isolator based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives, such as optocoupler devices and other integrated couplers. Unlike other optocoupler alternatives, this isolator has a patented refresh feature that ensures DC correctness in the absence of input logic transitions. Typical applications include general-purpose multichannel isolation, data converter isolation, industrial field bus isolation, hybrid electric vehicles, battery monitor and motor drive. Complies with UL recognition: 3000Vrms for 1minute per UL 1577, CSA component acceptance notice 5A, VDE certificate of conformity, DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12.
