The ADUM1411ARWZ-RL is an Analog Devices general-purpose four-channel digital isolator based on the company's i Coupler magnetic isolation technology, supplied in a wide-body 16-pin SOIC (300 mil). Its four unidirectional channels are split three in one direction and one in the reverse, so a single package can carry both outbound and return signals across the isolation barrier. Analog Devices rates the ADUM1411ARWZ-RL at up to 10 Mbps data rate with 100 ns propagation delay, 50 ns turn-on delay and 40 ns pulse width distortion, operating from a 2.7 V to 5.5 V supply at about 4 mA. The device does not include isolated power, is RoHS compliant, and is rated -40 C to +105 C.

Digital isolators replace optocouplers where a signal must cross a galvanic barrier to break ground loops, protect low-voltage logic from a high-voltage or noisy domain, or satisfy safety separation requirements. Magnetic i Coupler isolation is preferred over optical because it does not degrade with LED aging and delivers tighter timing, which is why the ADUM1411ARWZ-RL supports 10 Mbps with 100 ns delay. The 3/1 channel split matches common serial buses such as SPI, where clock, chip select and data-out go one way and data-in returns. Typical applications include industrial fieldbus and motor drives, isolated data acquisition, medical equipment, power supply control and battery management, and typical buyers are industrial automation, medical and power electronics designers.
