It runs at 1 Mbps with a 2500 Vrms isolation rating, which puts it squarely in the sweet spot for industrial fieldbus isolation — CAN, RS-485, Modbus, and general-purpose SPI isolation where you need three forward channels and one reverse channel (the 3/1 input split on this part). The wide-body 16-SOIC package (7.50 mm body width) gives you the creepage distance for 240 VAC reinforced isolation without moving to a larger footprint. ## 25 kV/µs CMTI — the spec that keeps the bus clean during a switching event Common-mode transient immunity is the spec that separates a working isolator from one that glitches when a motor drive or PSU switches. At 25 kV/µs minimum, this part handles the fast common-mode slewing you see in IGBT gate-drive circuits and industrial power stages. The 100 ns max propagation delay (both directions) and 40 ns max pulse-width distortion mean the timing skew across channels stays tight enough for synchronous interfaces like SPI at 1 Mbps.","metaTitle":"ADUM3401ARWZ-RL iCoupler Digital Isolator, 1 Mbps, 2500 Vrms","metaDescription":"ADI ADUM3401ARWZ-RL 4-channel general-purpose digital isolator. 1 Mbps data rate, 2500 Vrms isolation, 25 kV/µs CMTI, 3V-5.5V supply.

This is the standard speed for industrial fieldbus isolation — CAN, RS-485, Modbus — and for general-purpose SPI isolation at moderate clock rates. If you need higher speed, the ADuM140x family offers 10 Mbps and 90 Mbps variants in the same package footprint."},{"question":"Is ADUM3401ARWZ compatible with 3.3V logic?","answer":"Yes."},{"question":"What is the equivalent or replacement for ADUM3401ARWZ?","answer":"The closest functional sibling is the ADUM3402ARWZ-RL, which has the same 1 Mbps data rate, 2500 Vrms isolation, and 16-SOIC wide-body package but uses a 2/2 channel direction split instead of the 3/1 split on this part. For a 5 kV isolation variant with the same 3/1 channel split, look at the ADUM4401ARWZ-RL. Neither is a drop-in replacement — the channel direction assignment differs — but both share the same package and most electrical ratings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM3401ARWZ-RL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM3401ARWZ-RL when reusing this data.
