It provides 2500Vrms galvanic isolation across four unidirectional channels, with two channels going each direction (inputs side 1/side 2: 2/2). ## 25 Mbps data rate and signal timing — what matters for the bus With a 25 Mbps data rate and typical rise/fall times of 2.5 ns, this part handles SPI, UART, and general-purpose digital signalling cleanly. The 60 ns max propagation delay (tpLH/tpHL) is symmetric, which simplifies timing closure in bidirectional handshake lines. The 6 ns max pulse-width distortion means the duty cycle stays tight — important for PWM-like signals where edge symmetry matters. Common-mode transient immunity is rated at 25 kV/µs minimum, so it holds its state through fast voltage transients common in motor-drive and automotive 48 V bus environments. ## Power supply and voltage range The integrated isolated DC-DC converter generates a regulated output on the isolated side, so you don't need a separate transformer or isolated module for low-power side supplies — it's all in the 16-SOIC. That saves board area and BOM count in applications like isolated sensor interfaces or CAN/RS-485 transceiver power. ## Automotive grade and temperature range This part carries an Automotive grade designation, meaning it is qualified for the reliability and temperature demands of automotive applications. ## Package and rework notes The wide-body SOIC has enough pin pitch and thermal mass that a hot-air station at 300°C to 320°C with a fine nozzle lifts it cleanly — just preheat the board to 100°C to avoid pad lift on the inner rows.","metaTitle":"ADUM5402WCRWZ-1RL Digital Isolator, 25Mbps, 2500Vrms","metaDescription":"ADUM5402WCRWZ-1RL quad-channel digital isolator with integrated isolated power. 25Mbps, 2500Vrms isolation, automotive grade, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"2/2","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":"$18.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$18.37000","currency":"USD"},{"qty":10,"price":"$16.88100","currency":"USD"},{"qty":25,"price":"$16.18120","currency":"USD"},{"qty":100,"price":"$14.25700","currency":"USD"},{"qty":250,"price":"$13.55724","currency":"USD"},{"qty":500,"price":"$12.68256","currency":"USD"},{"qty":1000,"price":"$11.63298","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6eb96a9a812d635fb2f30fb59fbee33f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM5402WCRWZ-1RL provide isolated power?","answer":"Yes. The ADUM5402WCRWZ-1RL integrates an isolated DC-DC converter (IsoPower) that generates a regulated output on the isolated side, eliminating the need for a separate isolated power module for low-power side supplies."},{"question":"Is ADUM5402WCRWZ-1RL compatible with 5V logic?","answer":"Yes."},{"question":"Can ADUM5402WCRWZ-1RL be used for SPI isolation?","answer":"Yes, with the right channel assignment. The part has four unidirectional channels (2 inputs side 1, 2 inputs side 2), which can handle SPI's MOSI, MISO, and one clock or chip-select line. The 25 Mbps data rate supports standard SPI speeds up to 25 MHz, and the 60 ns propagation delay is manageable for most SPI bus timing budgets."},{"question":"Is ADUM5402WCRWZ-1RL a direct replacement for ADUM5402WCRWZ?","answer":"The ADUM5402WCRWZ-1RL is functionally identical to the ADUM5402CRWZ (same channel count, data rate, isolation voltage, and package), but the ADUM5402CRWZ is the non-automotive grade variant (commercial/industrial temperature range). The ADUM5402WCRWZ-1RL carries an Automotive grade designation and the -1RL suffix indicates Tape & Reel packaging. For automotive or high-reliability applications, the WCRWZ-1RL is the correct choice; for commercial designs, the CRWZ may be a lower-cost alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM5402WCRWZ-1RL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM5402WCRWZ-1RL when reusing this data.
