The ADUM120N0WBRZ-RL7 is a two-channel, general-purpose digital isolator from Analog Devices, built around iCoupler magnetic coupling technology. It pushes 150 Mbps per channel with a typical propagation delay of 13 ns and pulse-width distortion under 3 ns, which keeps the signal integrity tight for high-speed SPI, UART, or CAN lines crossing an isolation boundary.
Supply flexibility and CMTI — why the 1.8V to 5.5V range matters
The supply range from 1.8V to 5.5V on both sides lets you run the isolator from a 1.8V FPGA bank on one side and a 5V MCU on the other without a level shifter. That saves a part and a trace. The 100 kV/µs common-mode transient immunity is the spec that matters when this isolator sits between a motor-drive PWM and a controller — it rejects the fast dV/dt edges that would otherwise glitch the data stream. Unidirectional channels mean Side 1 drives Side 2, so plan the signal direction before layout.
Automotive series, active lifecycle, ROHS3
This part carries the Automotive series designation, which means it is built and tested to automotive-grade requirements — not just the temperature range, but the quality and reliability processes behind it. ROHS3 compliant, no exemptions. No official replacement exists because none is needed — it is the current-generation part.
