ADuM140/1/2 and ADuM240/1/2 Quad Channel Isolators with CMOS Technology

ADI's family of quad-channel digital isolators are based on their iCoupler technology. The parts families include ADuM140/ADuM141/AduM142 and ADuM240/ADuM241/AduM242. These isolators combine high-speed complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, providing 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 3 ns at 5 V operations. Channel matching is tight at 3.0 ns (maximum).

The ADuM140/ADuM141/AduM142 and ADuM240/ADuM241/AduM242's data channels are independent and are available in a variety of configurations of 4/0, 3/1, and 2/2 options with a withstand voltage rating of up to 5.0 kV_RMS. The devices operate with the supply voltage on either side ranging from 1.8 V to 5 V, providing compatibility with lower-voltage systems as well as enabling voltage translation functionality across the isolation barrier.
