Rated for 5000Vrms isolation and 25Mbps data rate, it fits applications like industrial fieldbus isolation, motor-drive interface, medical patient-connect circuits, and any board where you need to pass digital signals across a safety barrier without adding a second power converter. The 5000Vrms isolation rating is the key spec for reinforced insulation in mains-connected equipment. It means this part can sit on a 240VAC line side and talk to a low-voltage controller without compromising safety — think VFD control signals, PLC I/O modules, or isolated sensor interfaces. The 25Mbps data rate handles SPI clocks, UART streams, and most parallel GPIO isolation cleanly. Propagation delay is 60ns max (both edges), and pulse-width distortion stays under 6ns, so timing margins for a 10MHz SPI bus are comfortable. Common-mode transient immunity is rated at 25kV/µs minimum, which keeps data intact during fast voltage swings on the isolation barrier — important in motor-drive and inverter environments where switching transients are brutal. ## Integrated isolated power — no external transformer needed The IsoPower® block inside the ADUM6400CRWZ generates a regulated output voltage on the isolated side from the 3V to 5.5V input supply. That means you do not need a separate isolated DC-DC module, a flyback transformer, or an extra regulator — the part itself provides the isolated power rail. The four channels are all unidirectional and all on the same side (inputs side 1 / side 2 = 4/0), so this variant is set up for data flowing from the primary to the isolated side. For bidirectional or mixed-direction isolation, look at the ADUM6402 or ADUM6403 variants in the same package. ## Active lifecycle — no end-of-life concern for new designs ROHS3 compliant.","metaTitle":"ADUM6400CRWZ Digital Isolator, 5000Vrms, 25Mbps, 16-SOIC","metaDescription":"ADI ADUM6400CRWZ general-purpose digital isolator with integrated IsoPower®. 4 unidirectional channels, 25Mbps data rate, 5000Vrms isolation, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"IsoPower®, iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"IsoPower®, iCoupler®","Package":"Tube","Data Rate":"25Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","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":"4/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"6ns","Propagation Delay tpLH / tpHL (Max)":"60ns, 60ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.18","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$17.18000","currency":"USD"},{"qty":10,"price":"$15.78900","currency":"USD"},{"qty":25,"price":"$15.13480","currency":"USD"},{"qty":100,"price":"$13.33500","currency":"USD"},{"qty":250,"price":"$12.68056","currency":"USD"},{"qty":500,"price":"$11.86244","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/64cbf3e9142c9771c928705455ac2af4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM6400CRWZ include isolated power?","answer":"Yes, it integrates an isolated DC-DC converter (IsoPower®) on-chip, so no external transformer or separate isolated supply module is needed."},{"question":"What is the difference between ADUM6400CRWZ and ADUM6400ARWZ?","answer":"The ADUM6400CRWZ is the 25Mbps speed grade with 60ns propagation delay; the ADUM6400ARWZ is the 1Mbps speed grade with 100ns propagation delay.

With a 25Mbps data rate and 60ns propagation delay, it handles SPI clocks up to 10MHz with comfortable timing margin. The unidirectional channel arrangement (4 inputs on side 1, 0 on side 2) means it works for SPI signals all flowing one direction — for bidirectional SPI (MISO returning), consider the ADUM6402 or ADUM6403 variants with mixed input/output channels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM6400CRWZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM6400CRWZ when reusing this data.
