It uses magnetic coupling to provide 3750 Vrms of galvanic isolation across seven unidirectional channels — five on side 1, two on side 2 — matching the typical SPI signal set plus a few control or interrupt lines. Data rate is rated at 2 Mbps, which comfortably handles SPI clock speeds up to 2 MHz with propagation delay of 25 ns max and pulse width distortion under 3 ns. ## Package and footprint No isolated power converter is integrated — the part is a pure signal isolator, so each side needs its own supply rail.","metaTitle":"ADUM3151ARSZ-RL7 SPI Digital Isolator, 7-Ch, 3750Vrms","metaDescription":"ADUM3151ARSZ-RL7 SPI digital isolator from ADI's iCoupler series: 7 unidirectional channels, 2 Mbps data rate, 3750 Vrms isolation, -40 to 125°C.","metaKeywords":null},"attributes":{"series":"iCoupler®, SPIsolator™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"SPI","Series":"iCoupler®, SPIsolator™","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":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"7","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"5/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"25ns, 25ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.79","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.79000","currency":"USD"},{"qty":10,"price":"$6.13100","currency":"USD"},{"qty":25,"price":"$5.84520","currency":"USD"},{"qty":100,"price":"$5.07550","currency":"USD"},{"qty":250,"price":"$4.84736","currency":"USD"},{"qty":500,"price":"$4.41968","currency":"USD"},{"qty":1000,"price":"$4.03500","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM3151_3152_3153.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADUM3151ARSZ-RL7 RoHS compliant and lead-free?","answer":"Yes, the ADUM3151ARSZ-RL7 is ROHS3 compliant, meaning it is lead-free and meets the latest RoHS directive."},{"question":"What is the isolation rating of ADUM3151ARSZ-RL7 and does it support 3.3V/5V dual supply?","answer":"Isolation is rated at 3750 Vrms."},{"question":"Can ADUM3151ARSZ-RL7 replace ADUM3151ARSZ?","answer":"The ADUM3151ARSZ-RL7 is functionally identical to the ADUM3151ARSZ — same SPI isolator, same channel count, same package.
