ADuM744x Digital Isolator

ADI's ADuM744x series comprises 4-channel digital isolators that combine high speed CMOS and monolithic air core transformer technologies. These isolation components provide outstanding performance characteristics superior to alternatives, such as optocoupler devices and other integrated couplers.

ADuM744x quad 1 kV digital isolation devices are packaged in small, 16-lead QSOPs. With most 4-channel isolators available in 16-lead wide SOIC packages, the ADuM744x frees almost 70% of board space and yet withstand high isolation voltage and meet regulatory requirements such as UL and CSA standards (pending). In addition to the space savings, the ADuM744x offers a lower price than 2.5 kV or 5 kV isolators where only functional isolation is needed.
