It is designed for general-purpose isolation in industrial automation, motor drives, medical equipment, and isolated SPI/UART interfaces where galvanic isolation is required for safety or noise immunity. The 1Mbps data rate is the practical throughput ceiling for this part — adequate for isolated RS-485, I2C, or low-speed SPI links. If your design needs faster isolation, the iCoupler family includes 10Mbps and 150Mbps variants, but the trade-off is higher propagation delay and supply current. The 25kV/µs common-mode transient immunity is the spec that matters in motor-drive or inverter environments: fast-switching SiC or IGBT stages can inject several kV/µs across the barrier. This part's CMTI rating ensures the output doesn't glitch when the ground plane jumps. For reference, many lower-cost capacitive isolators spec 15kV/µs or less — the margin here buys robustness in noisy field wiring. Supply voltage range of 3V to 5.5V means the same part can sit on a 3.3V FPGA bank or a 5V PLC backplane without a level translator. The 3/1 input-to-output channel count — three channels driving from Side 1 to Side 2, one channel the opposite direction — suits half-duplex interfaces like RS-485 with a direction-control signal, or a three-wire SPI plus a single interrupt line back. ## Package and footprint — 16-SOIC wide-body considerations Housed in a 16-SOIC wide-body package (7.50mm body width), this isolator requires a wider PCB footprint than the narrow 3.90mm SOIC-16. The wider body provides the creepage distance needed to sustain the 5000Vrms isolation rating — expect a minimum of 8mm clearance between primary and secondary sides on the PCB layout. Surface-mount assembly is standard; no exposed thermal pad, so thermal dissipation is through the leads and the board copper. The 105°C ceiling is lower than the 125°C found on some automotive-grade isolators, so check the ambient plus self-heating if the part sits near a hot power stage or in a sealed enclosure.","metaTitle":"ADUM4401ARWZ-RL iCoupler Digital Isolator, 5000Vrms, 1Mbps","metaDescription":"ADI ADUM4401ARWZ-RL iCoupler 4-channel digital isolator, 5000Vrms isolation, 1Mbps data rate, 25kV/µs CMTI, -40°C to 105°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"40ns","Propagation Delay tpLH / tpHL (Max)":"100ns, 100ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.82000","currency":"USD"},{"qty":10,"price":"$7.96900","currency":"USD"},{"qty":25,"price":"$7.59880","currency":"USD"},{"qty":100,"price":"$6.59790","currency":"USD"},{"qty":250,"price":"$6.30140","currency":"USD"},{"qty":500,"price":"$5.74538","currency":"USD"},{"qty":1000,"price":"$5.00404","currency":"USD"},{"qty":2000,"price":"$4.81871","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM4400_4401_4402.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to ADUM4401ARWZ-RL?","answer":"Within the same iCoupler family, the ADUM4401ARIZ is the tube-packaged equivalent for low-volume builds. The ADUM2401ARWZ-RL is functionally identical — same 4-channel unidirectional isolation at 5000Vrms and 1Mbps — but uses a different internal channel mapping. The ADUM1411ARWZ-RL offers the same channel count and data rate but with a lower 3750Vrms isolation rating, suitable for applications that don't require reinforced isolation."},{"question":"Does ADUM4401ARWZ-RL support 1Mbps data rate?","answer":"Yes, the data rate is specified at 1Mbps. The propagation delay is 100ns max with pulse-width distortion of 40ns max, so the timing budget is tight for daisy-chained SPI at full speed — account for the 100ns per device in your bus timing analysis."},{"question":"Can ADUM4401ARWZ-RL be used with a 3.3V supply?","answer":"Yes, the supply voltage range is 3V to 5.5V, so it operates on a 3.3V rail directly. Both sides of the isolator must be powered within this range; the part does not provide isolated power, so each side needs its own supply."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM4401ARWZ-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/ADUM4401ARWZ-RL when reusing this data.
