The ADUM226N1BRIZ is a two-channel, unidirectional digital isolator from Analog Devices' iCoupler series, built with magnetic coupling technology. The 150 Mbps data rate covers most high-speed serial protocols — SPI up to 75 MHz clock, UART at any baud rate, and CAN FD at the full 5 Mbps. The 13 ns propagation delay (max) and 3 ns pulse-width distortion keep timing margins tight enough for back-to-back transactions without dead cycles.
75 kV/µs CMTI — why it matters for motor drives and inverters
Common-mode transient immunity of 75 kV/µs (minimum) is the spec that separates this part from older isolators. In a motor-drive or solar-inverter environment, fast IGBT switching edges can inject several kV/µs of common-mode noise across the isolation barrier. A CMTI rating below 50 kV/µs risks data corruption or latch-up; at 75 kV/µs the ADUM226N1BRIZ maintains signal integrity through those transients without external filtering.
