150 Mbps, 2-channel unidirectional isolator in 8-SOIC
The Analog Devices ADUM120N1BRZ-RL7 is a 2-channel, unidirectional digital isolator from the iCoupler® series, built on magnetic coupling technology. It delivers a 150 Mbps data rate across a 3000 Vrms isolation barrier, with a typical rise/fall time of 2.5 ns and propagation delay of 13 ns max. Common applications include SPI, UART, and general-purpose signal isolation in motor drives, power supplies, industrial automation, and medical equipment where galvanic isolation is required.
75 kV/µs CMTI — keeps data clean in noisy environments
The minimum common-mode transient immunity of 75 kV/µs is the spec that matters when this isolator sits between a microcontroller and a gate driver in a motor inverter or a switching power supply. That rating means the output won't glitch when a fast voltage transient slams across the isolation barrier — a common failure point in industrial drives. The 3 ns max pulse-width distortion also helps maintain signal integrity for edge-sensitive protocols like SPI.
Active lifecycle, ROHS3, and supply-range flexibility
The 8-SOIC footprint is a common, rework-friendly package that fits standard pick-and-place and hand-soldering workflows.
