Two-channel unidirectional isolation in an 8-SOIC footprint
The ADUM1280BRZ-RL7 is a 2-channel, unidirectional digital isolator from the iCoupler series, using magnetic coupling to transfer digital signals across a 3000 Vrms isolation barrier. 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.
