نظرة عامة على المنتج
The ADUM1200ARZ-RL7 is a dual-channel digital isolator manufactured by Analog Devices, based on the proprietary iCoupler magnetic coupling technology. Housed in an 8-lead narrow-body SOIC package, it provides galvanic isolation of 2500 Vrms (UL 1577) with a working voltage of 560 Vpeak (VDE 0884-17). The device features two same-direction (2/0) isolation channels, supporting data rates up to 1 Mbps (A-grade) with a maximum propagation delay of 150 ns.
