Overview
The ADuM261N0BRIZ-RL, produced by Analog Devices Inc., is a 6-channel digital isolator that utilizes Analog Devices' iCoupler technology. This component combines high-speed data transfer with robust isolation, making it suitable for a variety of applications requiring high reliability and noise immunity. The device operates with supply voltages ranging from 1.7 V to 5.5 V, enabling compatibility with lower voltage systems and voltage translation across the isolation barrier. It ensures dc correctness even in the absence of input logic transitions and offers two fail-safe options for output states when the input power supply is not applied.
