It delivers a 600 Mbps data rate per channel with a 4.5ns propagation delay, making it suitable for high-speed serial links where galvanic isolation is required. The 5000 Vrms isolation rating and 25 kV/µs common-mode transient immunity (CMTI) target industrial motor drives, inverter systems, and medical equipment where fast voltage transients and safety isolation are design constraints. ## 5000 Vrms isolation — what it buys you The 5000 Vrms isolation voltage is a reinforced-grade rating, not basic isolation. That matters when the isolator sits between a 2.5V LVDS controller and a high-voltage domain in motor drives, grid-tied inverters, or patient-connected medical electronics. The 25 kV/µs CMTI ensures the data link stays intact when a fast common-mode transient — say from an IGBT switching event — slams across the isolation barrier. At 0.35ns rise and fall times, the edges are clean enough for 600 Mbps signaling without excessive jitter, but the fast edges also mean the PCB layout around the SOIC-20 footprint needs controlled impedance traces and a solid ground plane under the isolation gap. ## 2.5V supply rail — not a 3.3V part The ADN4651BRWZ runs on a 2.375V to 2.625V supply — a tight 2.5V ±5% rail. This is not a generic 3.3V or 5V isolator; it is designed specifically for LVDS signal chains that operate at 2.5V. If your system already has a 2.5V rail for the LVDS transceiver, this part drops in. If you are trying to interface with a 3.3V logic domain, you will need level translation on the input side or a different isolator variant. The unidirectional channel configuration (one input on side 1, one input on side 2) supports a single LVDS pair in each direction, which matches point-to-point links where the data flow is known at design time. ## Active lifecycle and compliance For dual-sourcing flexibility, the ADN4651BRSZ-RL7 is a functional peer with the same 600 Mbps data rate and 1/1 input configuration but rated at 3750 Vrms isolation in a smaller package variant — a trade-off of isolation voltage for board area when 5000 Vrms is not required.","metaTitle":"ADN4651BRWZ LVDS Isolator, 600 Mbps, 5000 Vrms, iCoupler","metaDescription":"ADN4651BRWZ from Analog Devices: 2-channel unidirectional LVDS isolator, 600 Mbps data rate, 5000 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":"Tube","Data Rate":"600Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 2.625V","Number of Channels":"2","Voltage - Isolation":"5000Vrms","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-SOIC","Propagation Delay tpLH / tpHL (Max)":"4.5ns, 4.5ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.33","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$15.33000","currency":"USD"},{"qty":10,"price":"$14.09300","currency":"USD"},{"qty":25,"price":"$13.50920","currency":"USD"},{"qty":100,"price":"$11.90270","currency":"USD"},{"qty":250,"price":"$11.31856","currency":"USD"},{"qty":500,"price":"$10.58834","currency":"USD"},{"qty":1000,"price":"$9.71206","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADN4650-4651-4652.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADN4651BRWZ RoHS compliant and lead-free?","answer":"Yes, the ADN4651BRWZ is ROHS3 compliant per the manufacturer's listing."},{"question":"Can ADN4651BRWZ be used with a 2.5V supply?","answer":"Yes, the ADN4651BRWZ operates from a 2.375V to 2.625V supply, which is a 2.5V nominal rail with ±5% tolerance."},{"question":"Are there any equivalent or replacement parts for ADN4651BRWZ?","answer":"The ADN4652BRWZ-RL7 offers the same 5000 Vrms isolation with a different channel direction mapping.
