The ADUM3402CRWZ-RL is a 4-channel, unidirectional digital isolator from ADI's iCoupler series, built around magnetic coupling technology. It delivers 90 Mbps data rate per channel with 2.5 ns typical rise/fall times, 32 ns max propagation delay, and 2 ns max pulse-width distortion. The 2/2 input/output split suits designs needing two isolated upstream and two downstream paths.
2500 Vrms isolation and 25 kV/µs CMTI — where it works
Rated for 2500 Vrms isolation, this part covers reinforced isolation requirements in industrial automation, motor drives, and medical equipment where the safety barrier must hold off transient overvoltages. The 25 kV/µs minimum common-mode transient immunity (CMTI) is the spec that matters when the isolator sits across a noisy switching node — a motor-drive inverter or a mains-referenced sensor — because it guarantees the output does not glitch when the ground plane jumps.
Supply range and package — board-level fit
Housed in a 16-SOIC wide-body (7.50 mm width) package, the footprint matches standard SOIC-16W land patterns.
Lifecycle and compliance
ADI lists the ADUM3402CRWZ-RL as Active product status. ROHS3 compliant per the ledger, which covers the current EU RoHS exemption list.
