Its 4/3 input-side/side-2 split maps directly to a full SPI bus: SCK, MOSI, MISO, and up to three chip-select lines on the primary side, with three secondary-side signals for interrupt or handshake lines. This isn't a generic four-channel isolator you have to jury-rig — the channel count and direction are purpose-built for SPI, so you don't waste channels or add external logic. The 34 Mbps data rate gives you headroom for SPI clocks up to 17 MHz in double-edge sampling mode, or 34 MHz single-edge — well past what most MCU SPI peripherals can generate. Propagation delay is 14 ns max in either direction, with 2 ns pulse-width distortion, so the timing budget stays tight even across the isolation barrier. Isolation is rated at 3750 Vrms, which satisfies reinforced insulation requirements for mains-connected industrial equipment per IEC 60950-1 and IEC 62368-1. The 25 kV/µs common-mode transient immunity (CMTI) is the spec that matters in motor-drive or inverter applications — it prevents data corruption when the power stage switches at high dV/dt. ## Temperature range and operating environment No isolated power on-chip — you'll need a separate isolated DC-DC converter for the secondary-side supply. ## Lifecycle — active, no end-of-life watch needed No last-time-buy notices, no end-of-life risk for the foreseeable future. ROHS3 compliant, so it passes European and California regulatory requirements without an exemption certificate. For a new-design BOM, this part is a safe socket — you won't be scrambling for a replacement mid-production.","metaTitle":"ADUM3152BRSZ-RL7 SPI Digital Isolator, 34 Mbps, 20-SSOP","metaDescription":"ADUM3152BRSZ-RL7 SPI digital isolator from ADI's iCoupler/SPIsolator series. 7 unidirectional channels, 34 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":"34Mbps","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":"4/3","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"2ns","Propagation Delay tpLH / tpHL (Max)":"14ns, 14ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.98052","stockQuantity":0,"priceTiers":[{"qty":500,"price":"$5.98052","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM3151_3152_3153.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the ADUM3152BRSZ-RL7's data rate and what does that mean for my SPI clock?","answer":"The ADUM3152BRSZ-RL7 supports a 34 Mbps data rate. For a standard SPI bus, that translates to a 17 MHz clock in double-edge sampling mode or 34 MHz in single-edge mode — enough headroom for most MCU SPI peripherals.
