Overview
The ADUM161N0BRZ-RL7, produced by Analog Devices Inc., is a 6-channel digital isolator based on the company's iCoupler® technology. This component combines high-speed, complementary metal-oxide semiconductor (CMOS), and monolithic air core transformer technology to provide superior performance characteristics compared to other isolation methods such as optocouplers. The device is designed for general-purpose multichannel isolation and is particularly useful in applications requiring high-speed data transfer and robust isolation barriers.
