The ADUM4402BRWZ-RL: 4-channel digital isolator, magnetic coupling, 5000 Vrms isolation. 2/2 channel split, 10 Mbps data rate, 50 ns propagation delay, 25 kV/µs CMTI.
Runs on a single 3 V to 5.5 V supply on both sides — no separate secondary rail needed. Surface-mount 16-SOIC (7.50 mm wide) footprint, available in Tape & Reel or Cut Tape.
Yes. Supply range is 3 V to 5.5 V on each side, so you can run one side at 3.3 V and the other at 5 V for level translation across the isolation barrier.
The ADUM2401BRWZ-RL is the closest sibling in the same iCoupler family — same 5000 Vrms, 10 Mbps, 16-SOIC package — but its channel direction is 3 inputs on Side 1 and 1 input on Side 2, not the 2/2 split of the ADUM4402. Choose based on your direction needs.
