Overview
The ADUM3210ARZ-RL7 is a dual-channel digital isolator produced by Analog Devices Inc., utilizing their proprietary iCoupler® technology. This component combines high-speed CMOS and monolithic transformer technology to provide superior performance characteristics compared to traditional optocouplers. It eliminates the design difficulties associated with optocouplers, such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects. The ADUM3210ARZ-RL7 consumes significantly less power than optocouplers, typically one-tenth to one-sixth at comparable signal data rates, and does not require external drivers or discrete components.
