It passes digital signals across a 2500Vrms isolation barrier at up to 90Mbps, with three channels driving from Side 1 to Side 2 and one channel going the reverse direction. The wide-body 16-SOIC package gives the creepage distance needed to maintain the isolation rating across the board. ## 90 Mbps and 2.5 ns edges — what they mean for signal integrity The 90Mbps data rate with 2.5ns typical rise and fall times means this part can handle fast serial interfaces like SPI at 20-30 MHz clock rates with clean edges. Propagation delay is 32ns max in either direction, and pulse-width distortion is held to 2ns max — tight enough that duty-cycle-sensitive signals like PWM or Manchester-encoded data pass through without significant skew. The 25kV/µs common-mode transient immunity is the spec that matters when this isolator sits on a motor drive or inverter board: fast-switching IGBTs can slam several thousand volts per microsecond across the barrier, and this part keeps its output state through that transient rather than glitching. ## Supply flexibility and temperature range Supply voltage spans 2.7V to 5.5V on both sides, so you can run the isolated side at a different logic level than the controller side — 3.3V on one side and 5V on the other, for example — without a separate level shifter. No isolated power converter is built in; each side needs its own local supply rail.","metaTitle":"ADUM1401CRWZ iCoupler Digital Isolator, 90Mbps, 2500Vrms","metaDescription":"ADI ADUM1401CRWZ general-purpose 4-channel digital isolator with magnetic coupling, 90Mbps data rate, 2500Vrms isolation, -40°C to 105°C.

The 3/1 channel direction (three forward, one reverse) maps directly to the four-wire SPI bus: SCLK, MOSI, and chip select on the three forward channels, MISO on the single reverse channel. The 90Mbps data rate supports SPI clock rates well above what most MCUs and sensors use."},{"question":"What is the closest pin-compatible alternative to ADUM1401CRWZ?","answer":"The ADUM1400 is the same 4-channel unidirectional isolator in the same 16-SOIC package, but with all four channels going the same direction (4/0). The ADUM1401CRWZ has the 3/1 split. If your design needs the reverse channel, the ADUM1400 will not work without rewiring. The ADUM1402 offers a 2/2 split. Check the channel direction requirement before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM1401CRWZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM1401CRWZ when reusing this data.
