Dual-Channel Digital Isolators Data Sheet ADuM1200/ADuM1201 The typical optocoupler concerns regarding uncertain current FEATURES transfer ratios, nonlinear transfer functions, and temperature and Narrow body, RoHS-compliant, SOIC 8-lead package lifetime effects are eliminated with the simple iCoupler digital Low power operation interfaces and stable performance characteristics. The need for 5 V operation external drivers and other discrete components is eliminated 1.1 mA per channel maximum at 0 Mbps to 2 Mbps with these iCoupler products. Furthermore, iCoupler devices 3.7 mA per channel maximum at 10 Mbps consume one-tenth to one-sixth the power of optocouplers at 8.2 mA per channel maximum at 25 Mbps comparable signal data rates. 3 V operation 0.8 mA per channel maximum at 0 Mbps to 2 Mbps The ADuM1200/ADuM1201 isolators provide two independent 2.2 mA per channel maximum at 10 Mbps isolation channels in a variety of channel configurations and 4.8 mA per channel maximum at 25 Mbps data rates (see the Ordering Guide). Both devices operate with Bidirectional communication the supply voltage on either side ranging from 2.7 V to 5.5 V, 3 V/5 V level translation providing compatibility with lower voltage systems as well as High temperature operation: 125C enabling a voltage translation functionality across the isolation High data rate: dc to 25 Mbps (NRZ) barrier. In addition, the ADuM1200/ADuM1201 provide low Precise timing characteristics pulse width distortion (<3 ns for CR grade) and tight channel- 3 ns maximum pulse width distortion to-channel matching (<3 ns for CR grade). Unlike other 3 ns maximum channel-to-channel matching optocoupler alternatives, the ADuM1200/ADuM1201 isolators High common-mode transient immunity: >25 kV/s have a patented refresh feature that ensures dc correctness in Safety and regulatory approvals the absence of input logic transitions and during power- UL recognition up/power-down conditions. 2500 V rms for 1 minute per UL 1577 The ADuM1200W and ADuM1201W are automotive grade CSA Component Acceptance Notice 5A versions qualified for 125C operation. See the Automotive VDE Certificate of Conformity Products section for more information.
