The Analog Devices ADUM226N1BRIZ-RL is a two-channel, unidirectional digital isolator from the iCoupler family, built around magnetic coupling. Its headline rating is 5000 Vrms isolation in a standard 8-SOIC wide-body package — that is reinforced-grade insulation for motor drives, industrial power supplies, medical equipment, and any design where a galvanic barrier must survive a 5 kV hipot test. The 150 Mbps data rate handles SPI, UART, and general-purpose logic isolation without bottlenecking the signal chain.
75 kV/µs CMTI — why it matters for motor drives and inverters
Common-mode transient immunity of 75 kV/µs minimum keeps data intact during fast ground-reference shifts. Propagation delay is 13 ns max in either direction, with pulse-width distortion held to 3 ns. That keeps the timing budget tight for isolated SPI or PWM signals where edge alignment matters.
No isolated power output on this variant — it is a pure signal isolator; the secondary-side supply must come from the board.
