ADuM225N Robust 5.0 kV rms Dual Channel Digital Isolator & 0 Reverse Channels & 8.3mm Creepage

The ADuM225N is a dual-channel digital isolator based on Analog Devices, Inc., 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 (PWD) of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum.

The ADuM225N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.0 kV rms (see the Ordering Guide). The devices operate with the supply voltage on either side ranging from 1.8 V to 5 V, providing compatibil¬ity with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.

Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. Two different fail-safe options are available, in which the outputs transition to a predetermined state when the input power supply is not applied or the inputs are disabled.
