The inputs are all on side 1 (2/0 configuration), so this part is a straight shot for isolating a two-wire digital signal path — think UART TX/RX, SPI clock and data, or general-purpose GPIO isolation where the direction is fixed. ## 25 kV/µs CMTI — built for noisy environments Common-mode transient immunity is rated at a minimum 25 kV/µs. That number matters when the isolator sits between a noisy motor-drive power stage and a sensitive controller — fast voltage transients across the barrier won't glitch the output. The 3 ns max pulse-width distortion keeps the pulse shape clean for timing-sensitive interfaces like SPI or PWM capture. ADI lists the ADUM1280BRZ-RL7 as Active.","metaTitle":"ADUM1280BRZ-RL7 iCoupler Digital Isolator, 25 Mbps","metaDescription":"ADUM1280BRZ-RL7 iCoupler digital isolator: 2-channel unidirectional, 25 Mbps data rate, 3000 Vrms isolation, -40°C to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"25Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"3000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"35ns, 35ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.83","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.83000","currency":"USD"},{"qty":10,"price":"$3.43700","currency":"USD"},{"qty":25,"price":"$3.24960","currency":"USD"},{"qty":100,"price":"$2.81640","currency":"USD"},{"qty":250,"price":"$2.67196","currency":"USD"},{"qty":500,"price":"$2.39754","currency":"USD"},{"qty":1000,"price":"$2.02202","currency":"USD"},{"qty":2000,"price":"$1.92092","currency":"USD"},{"qty":5000,"price":"$1.84870","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8e75547927d6f41e80c5c7dd03fbac65.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM1280BRZ-RL7 be used for SPI isolation?","answer":"Yes, with the 2/0 unidirectional channel configuration and 25 Mbps data rate, it can isolate SPI clock and one data line (e.g., SCLK and MOSI). For full-duplex SPI (MISO also needed), you would need a second isolator or a part with bidirectional channels. The 3 ns pulse-width distortion keeps the clock edge timing tight enough for most SPI buses up to 10-15 MHz."},{"question":"What is the closest pin-compatible alternative to ADUM1280BRZ-RL7?","answer":"The ADUM1200BRZ is a direct pin-compatible alternative within the same iCoupler family — same 2-channel unidirectional configuration, same 8-SOIC package, same isolation rating. The key difference is data rate: ADUM1200BRZ is rated for 10 Mbps, while ADUM1280BRZ-RL7 runs at 25 Mbps. If your design needs the higher speed, stick with the ADUM1280BRZ-RL7."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM1280BRZ-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/ADUM1280BRZ-RL7 when reusing this data.
