The 25kV/µs minimum common-mode transient immunity (CMTI) is the spec that matters in motor-drive and inverter environments where fast voltage slewing across the barrier can otherwise corrupt the data stream. Propagation delay is 180ns max each way, with 8ns max pulse-width distortion, so the timing budget stays predictable for synchronous interfaces like SPI at 2MHz clock. ## Industrial temperature range in a 16-QSOP footprint The 16-QSOP package (3.90mm body width) is a compact alternative to the wider SOIC-16 footprint, saving board area in multi-channel isolation banks. Rise and fall times are a clean 2ns typical, keeping edge-rate-induced emissions manageable. ## Active lifecycle — no near-term obsolescence concern ADI lists the ADUM1441ARQZ-RL7 as Active in production.","metaTitle":"ADUM1441ARQZ-RL7 iCoupler Digital Isolator, 2500Vrms, 4Ch","metaDescription":"ADUM1441ARQZ-RL7 iCoupler digital isolator: 2500Vrms isolation, 2Mbps, 4 unidirectional channels (3/1), -40°C to 125°C, 16-QSOP.","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":"2Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.25V ~ 3.6V","Number of Channels":"4","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2ns, 2ns","Supplier Device Package":"16-QSOP","Pulse Width Distortion (Max)":"8ns","Propagation Delay tpLH / tpHL (Max)":"180ns, 180ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.49000","currency":"USD"},{"qty":10,"price":"$5.86300","currency":"USD"},{"qty":25,"price":"$5.59040","currency":"USD"},{"qty":100,"price":"$4.85410","currency":"USD"},{"qty":250,"price":"$4.63592","currency":"USD"},{"qty":500,"price":"$4.22684","currency":"USD"},{"qty":1000,"price":"$3.68145","currency":"USD"},{"qty":2000,"price":"$3.54510","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/93aa2cbe2cc46113c0a7248fa663316e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional equivalent to ADUM1441ARQZ-RL7?","answer":"The ADUM1445ARQZ-RL7 is the closest same-series sibling. It shares the same 2Mbps data rate, 2500Vrms isolation, 16-QSOP package, and 25kV/µs CMTI, but its channel arrangement is 4/0 (all four inputs on side 1) instead of the 3/1 split on the ADUM1441.
