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.<\/p>\n

It provides 2500Vrms isolation (UL1577) with >25kV\/us common-mode transient immunity. The 2\/0 same-direction channels support 3V\/5V level translation across the isolation barrier. A-grade offers 1Mbps data rate with 150ns max propagation delay. Patent refresh circuitry ensures DC correctness during power-up\/down and idle states. Power consumption is 1\/10 to 1\/6 of equivalent optocouplers.","working_principle":"iCoupler technology integrates high-speed CMOS with on-chip micro-transformers. Input-side CMOS encodes digital signals and drives the transformer primary; electromagnetic coupling transfers signals to the secondary where output CMOS decodes them. A patent refresh circuit periodically refreshes output state during idle periods to maintain DC correctness. On-chip shielding blocks capacitive coupling paths between primary and secondary, achieving >25kV\/us CMTI. Dual independent channels each contain encoder, transformer, and decoder. The 2.7-5.5V supply range allows different voltages on each side for level translation across the isolation barrier.","pin_description":"
