Description

Product Overview

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.

Features

  • iCoupler technology replaces optocouplers with on-chip micro-transformers
  • Patent refresh circuit ensures DC correctness during idle and power transitions
  • 3 V / 5 V level translation across the isolation barrier
  • Power consumption only 1/10 to 1/6 of equivalent optocouplers
  • Safety certifications: UL 1577, CSA, VDE 0884-17, IEC 62368-1, IEC 61010-1, CQC GB4943.1

Applications

  • SPI interface and data converter isolation
  • RS-232 / RS-485 / RS-422 transceiver isolation
  • Digital fieldbus isolation (CAN, etc.)
  • HEV battery monitoring and motor drive
  • Multi-channel isolation in space-constrained systems

The ADUM1200ARZ-RL7 is a dual-channel digital isolator from Analog Devices using iCoupler magnetic coupling technology. 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.

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.
