That data rate covers most SPI clock lines up to 25 MHz without stretching the timing budget, so it fits directly between a 3.3 V MCU and an isolated peripheral without needing a slower fallback mode. The 2/2 input-to-output split gives you two channels each direction, which maps neatly to SPI (SCLK, MOSI, MISO, and one CS) or two independent UART links. ## Isolation voltage and transient immunity — where it sits in the cycle 3750 Vrms is the standard reinforced isolation level for industrial fieldbus, motor-drive feedback, and medical patient-interface barriers. The 25 kV/µs common-mode transient immunity means it holds the data through fast-switching inverter edges — a spec that matters more than the headline isolation number when the part sits between a gate driver and a controller on a motor drive. At 25 Mbps with 33 ns max propagation delay and 3 ns pulse-width distortion, the timing skew is tight enough to keep SPI frames intact across the barrier without extra deserializing. ## Supply rails and temperature range No isolated power on board; you supply Vdd on both sides separately. ## Lifecycle and supply posture ADI lists the ADUM3482BRSZ as Active product status, so there is no LTB window or EOL notice to watch. The part is ROHS3 compliant and ships in a 20-SSOP package.","metaTitle":"ADUM3482BRSZ iCoupler Digital Isolator, 25 Mbps, 3750 Vrms","metaDescription":"ADUM3482BRSZ general-purpose digital isolator with magnetic coupling, 4 unidirectional channels, 25 Mbps data rate, 3750 Vrms isolation.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tube","Data Rate":"25Mbps","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":"1.8V ~ 5.5V, 3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"33ns, 33ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.18","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.18000","currency":"USD"},{"qty":10,"price":"$5.58100","currency":"USD"},{"qty":25,"price":"$5.32120","currency":"USD"},{"qty":100,"price":"$4.62030","currency":"USD"},{"qty":250,"price":"$4.41268","currency":"USD"},{"qty":500,"price":"$4.02334","currency":"USD"},{"qty":1000,"price":"$3.50420","currency":"USD"},{"qty":2500,"price":"$3.37441","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM3480_3481_3482.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM3482BRSZ be used for SPI isolation?","answer":"Yes, the 25 Mbps data rate and 2/2 input-to-output channel split (two channels each direction) map directly to SPI signals — SCLK, MOSI, MISO, and one chip-select — without needing a slower fallback mode."},{"question":"Does ADUM3482BRSZ require an isolated power supply?","answer":"No, the ADUM3482BRSZ does not integrate an isolated DC-DC converter.
