ADuM160/1/2/3 Family of Six-Channel Digital Isolators for SPI Applications

ADI's ADuM160N / ADuM161N / ADuM162N / ADuM163N are 6-channel digital isolators based on their iCoupler technology. Combining high-speed complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion of less than 4.5 ns at 5 V operations. Channel-to-channel matching of propagation delay is tight at 4.0 ns (maximum).

The ADuM160N / ADuM161N / ADuM162N / ADuM163N data channel options are 3/3, 4/2, 5/1, and 6/0. These isolators can withstand voltage ratings of 3.0 kV_RMS and operate with the supply voltage on either side ranging from 1.7 V to 5.5 V, providing compatibility with lower-voltage systems as well as enabling voltage translation functionality across the isolation barrier.
