ADUM320N0WBRIZ-RL

The ADuM320N/ADuM321N1 are dual-channel digital isolators based on iCoupler technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and meet CISPR 32/EN 55032 Class B limits at 5 Mbps. The maximum propagation delay is 10 ns with a pulse width distortion of less than 3 ns at 5V operation. Channel matching is hard at 3.0 ns maximum. The ADuM320N/ADuM321N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.7kV RMS and 3.0kV RMS. The devices operate with the supply voltage on either side ranging from 2.25V to 5.5V providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. Two different fail-safe options are available, by which the outputs transition to a predetermined state when the input power supply is not applied.
