That means it can provide a regulated, isolated output voltage from its own internal oscillator and transformer — no separate isolated power module needed on the secondary side. The part is rated for 5000Vrms isolation and a minimum common-mode transient immunity of 25kV/µs, which puts it squarely in the industrial motor-drive and inverter class where high-voltage transients are the norm. The 1Mbps data rate with 100ns max propagation delay is fine for SPI, UART, and general-purpose GPIO isolation, but not for high-speed interfaces like CAN (typically 1Mbps but tighter timing) or full-speed USB. ## Channel direction and supply voltage — getting the fit right The channel arrangement is 1 input on Side 1 (the primary side) and 3 inputs on Side 2 (the isolated side). The supply range is 3V to 5.5V on both sides, so 3.3V or 5V logic rails work without a separate level shifter — but both sides must be powered within that window; the IsoPower converter generates its own isolated rail internally, not from an external secondary supply. ## Package and thermal handling Housed in a 16-SOIC wide-body package (7.50mm width) with surface-mount termination. The IsoPower converter runs its own internal switching at a few hundred kilohertz, so the usual SOIC-16 thermal dissipation applies — no exposed pad, so the junction-to-ambient path is through the leads and board copper. For continuous operation near 105°C ambient, ensure adequate copper pour on the secondary side to spread the converter's dissipation.","metaTitle":"ADUM6403ARWZ IsoPower Digital Isolator, 5000Vrms, 1Mbps","metaDescription":"ADI ADUM6403ARWZ quad-channel digital isolator with integrated IsoPower isolated DC-DC converter. 5000Vrms isolation, 1Mbps data rate, 25kV/µs CMTI.","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":"1Mbps","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":"1/3","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":"$15.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$15.76000","currency":"USD"},{"qty":10,"price":"$14.48300","currency":"USD"},{"qty":25,"price":"$13.88280","currency":"USD"},{"qty":100,"price":"$12.23200","currency":"USD"},{"qty":250,"price":"$11.63168","currency":"USD"},{"qty":500,"price":"$10.88124","currency":"USD"},{"qty":1000,"price":"$9.98072","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/64cbf3e9142c9771c928705455ac2af4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy ADUM6403ARWZ and get a price?","answer":"Submit an RFQ to receive a firm price and lead time."},{"question":"Does ADUM6403ARWZ provide isolated power on the secondary side?","answer":"Yes, the ADUM6403ARWZ integrates an IsoPower isolated DC-DC converter that generates a regulated, isolated output voltage on the secondary side — no external isolated power module required."},{"question":"What is the difference between ADUM6403ARWZ and ADUM6402ARWZ?","answer":"Both are quad-channel IsoPower digital isolators with 5000Vrms isolation, 1Mbps data rate, and the same package. The key difference is the input/output channel direction: the ADUM6403ARWZ has a 1/3 split (1 input on Side 1, 3 inputs on Side 2), while the ADUM6402ARWZ has a 2/2 split. Choose based on how many signals cross the barrier in each direction."},{"question":"Can ADUM6403ARWZ be used for CAN bus isolation?","answer":"The ADUM6403ARWZ has a 1Mbps data rate with 100ns propagation delay and 40ns pulse-width distortion. While CAN bus runs at up to 1Mbps, the timing margins are tight — the 100ns delay and 40ns distortion may not meet the loop-delay requirements of a standard CAN transceiver interface. For CAN isolation, consider a dedicated CAN isolator or a higher-speed digital isolator with lower propagation skew."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM6403ARWZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM6403ARWZ when reusing this data.
