Five-channel isolation at 150 Mbps — signal-integrity budget for isolated SPI/UART links
The ADUM250N0BRIZ is a five-channel, unidirectional digital isolator from Analog Devices' iCoupler series, using magnetic coupling to transfer data across a galvanic isolation barrier rated at 5000 Vrms. It supports a data rate of 150 Mbps with typical rise/fall times of 2.5 ns and a maximum propagation delay of 13 ns in either direction, making it suitable for high-speed serial interfaces such as SPI, UART, and parallel control signals where timing margin is tight.
75 kV/µs CMTI — common-mode transient immunity for motor-drive and inverter environments
With a minimum common-mode transient immunity of 75 kV/µs, this isolator maintains data integrity in the presence of fast voltage transients common in motor drives, solar inverters, and industrial power supplies.
Package and footprint — 16-SOIC wide-body with 7.50 mm width
The wide-body SOIC provides the creepage distance needed to maintain the 5000 Vrms isolation rating across the package. All five channels are unidirectional with all inputs on side 1 and all outputs on side 2, simplifying PCB layout for applications that require isolated data flow in one direction only.
