It delivers 3000Vrms isolation in an 8-SOIC footprint, with a 25Mbps data rate that comfortably handles SPI clocks, UART lines, and general-purpose logic-level isolation up to that speed. The 3000Vrms isolation rating is the spec that decides fit for reinforced insulation in mains-connected equipment. For a 230VAC motor drive or a 48V industrial bus, this holds margin for basic insulation; for 400V systems you'd step up to a higher-rated part. The 25Mbps data rate is enough for most isolated SPI (up to 20MHz clock) and asynchronous serial links without bit-rate compression. Propagation delay is 35ns max each direction, which keeps the bus-turnaround budget tight but workable for most control loops. CMTI of 25kV/µs minimum means the output stays clean when a fast common-mode transient slams across the barrier — exactly what happens in a half-bridge gate-drive node or a motor-phase current-sense circuit. If your system has SiC or GaN switches with sub-10ns edges, this CMTI is adequate; for slower IGBT edges it's overkill, but the margin costs nothing. Supply range of 3V to 5.5V on both sides lets this isolator bridge a 3.3V MCU domain to a 5V sensor or actuator interface without a level shifter. The unidirectional channel configuration (2 inputs on side 1, 0 on side 2) means all channels run the same direction — fine for isolated SPI (SCLK, MOSI) or two general-purpose output signals. If you need bidirectional channels, you'd look at the ADUM1280 or ADUM1281 variants. ## Package and thermal reality No isolated power on chip; you supply separate 3V to 5.5V rails on each side. ## Lifecycle and sourcing posture It is ROHS3 compliant. For dual-sourcing resilience, the iCoupler family includes pin-compatible siblings with different channel counts and directions — the ADUM1280 (2/0, 25Mbps) and ADUM1281 (1/1, 25Mbps) share the same 8-SOIC footprint and isolation rating.","metaTitle":"ADUM1285BRZ-RL7 iCoupler Digital Isolator, 25Mbps, 3000Vrms","metaDescription":"ADUM1285BRZ-RL7 iCoupler digital isolator: 2-channel unidirectional, 25Mbps data rate, 3000Vrms isolation, -40°C to 125°C.
