It delivers a 600 Mbps data rate per channel with a 4.5 ns propagation delay, making it suited for isolating high-speed serial interfaces like SPI, UART, or LVDS clock/data lines in industrial and telecom systems. The 3750 Vrms isolation rating and 25 kV/µs common-mode transient immunity (CMTI) allow it to sit across a galvanic isolation barrier in motor drives, grid-tied inverters, or medical equipment where fast voltage transients are present. The supply range is 2.375 V to 2.625 V, so the part runs from a 2.5 V rail — not 3.3 V or 1.8 V without a regulator. The 3750 Vrms isolation voltage is a 1-minute withstand rating, typical for reinforced single isolation in industrial and medical applications. The 25 kV/µs minimum CMTI is the spec that matters when the isolator bridges a noisy power stage: in a motor drive or switched-mode supply, the voltage across the barrier can slew at tens of kV/µs during switching events. If the isolator's CMTI is too low, data corruption or latch-up occurs. At 25 kV/µs, the ADN4651BRSZ-RL7 handles the edge rates from SiC and GaN half-bridges, not just IGBTs. ## 2.5 V supply — not a 3.3 V part The supply voltage is 2.375 V to 2.625 V, which is a 2.5 V nominal rail. This is narrower than the 3.0 V to 5.5 V range on many digital isolators. If the system runs 3.3 V LVDS, a local 2.5 V LDO is needed for this isolator. The LVDS I/O levels are CML-like and AC-coupled in many designs, so the supply mismatch is manageable, but the BOM must include the regulator. The 2.5 V rail also limits the input logic threshold: the VIH/VIL levels follow LVDS standards, not TTL or CMOS. ## 20-SSOP package and tape-and-reel suffix The part comes in a 20-lead SSOP body, 5.30 mm wide, surface-mount. The BRSZ base code shares the same 20-SSOP footprint and electrical specs across both suffixes. The iCoupler platform is a mature, multi-sourced process at ADI, so PCN frequency is low.","metaTitle":"ADN4651BRSZ-RL7 iCoupler LVDS Isolator, 600 Mbps, 3750 Vrms","metaDescription":"ADI ADN4651BRSZ-RL7 iCoupler magnetic LVDS isolator: 2 channels, 600 Mbps data rate, 3750 Vrms isolation, 25 kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"LVDS","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"600Mbps","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":"2.375V ~ 2.625V","Number of Channels":"2","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"0.35ns, 0.35ns (Max)","Supplier Device Package":"20-SSOP","Propagation Delay tpLH / tpHL (Max)":"4.5ns, 4.5ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.81000","currency":"USD"},{"qty":10,"price":"$12.69000","currency":"USD"},{"qty":25,"price":"$12.16400","currency":"USD"},{"qty":100,"price":"$10.71740","currency":"USD"},{"qty":250,"price":"$10.19140","currency":"USD"},{"qty":500,"price":"$9.53390","currency":"USD"},{"qty":1000,"price":"$8.74488","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADN4650-4651-4652.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the direct replacement or equivalent for ADN4651BRSZ-RL7?","answer":"The ADN4651BRSZ-RL7 has no direct replacement because it is an active part. The closest functional sibling is the ADN4652BRSZ-RL7, which is identical in data rate (600 Mbps), package (20-SSOP), and supply range, but the ADN4652 has its inputs on the opposite side (Side 1/Side 2 input count is 1/1, same as the ADN4651). The ADN4651BRWZ is the same isolator in a wider 20-SOIC package with 5000 Vrms isolation, for designs needing higher isolation voltage in a larger body."},{"question":"Can ADN4651BRSZ-RL7 be used for 3.3V LVDS isolation?","answer":"Not directly. The ADN4651BRSZ-RL7 requires a 2.375 V to 2.625 V supply. For 3.3 V LVDS isolation, a local 2.5 V regulator must be added to the BOM. The LVDS I/O levels are standard (350 mV swing typical) and AC-coupled in most designs, so the supply mismatch does not affect signal integrity, but the power rail must be generated."},{"question":"Is ADN4651BRSZ-RL7 the same as ADN4651BRSZ (non-tape/reel)?","answer":"Yes, the ADN4651BRSZ (tube) and ADN4651BRSZ-RL7 (tape-and-reel) are electrically identical — same die, same 20-SSOP package, same 600 Mbps data rate, same 3750 Vrms isolation. The only difference is the shipping medium: tube for low-volume or prototype builds, tape-and-reel for automated assembly."},{"question":"Is ADN4651BRSZ-RL7 compatible with 2.5V supplies?","answer":"Yes, the 2.375 V to 2.625 V supply range is centered on 2.5 V. A 2.5 V ±5% rail is within spec. The part will not operate from a 3.3 V or 1.8 V rail without regulation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADN4651BRSZ-RL7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADN4651BRSZ-RL7 when reusing this data.
