Overview
The ADUM3210ARZ is a dual-channel digital isolator produced by Analog Devices Inc. It is based on Analog Devices' iCoupler® technology, which combines high-speed CMOS and monolithic transformer technology to provide superior performance characteristics compared to traditional optocouplers. This isolator eliminates concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects, offering stable and reliable digital interfaces. The ADUM3210ARZ consumes significantly less power than optocouplers at comparable signal data rates and is certified by various safety standards including UL recognition, CSA, VDE, and DIN V VDE V 0884-10:2006-12, with a VIORM of 560V peak.
