Quad-Channel Digital Isolators Data Sheet ADuM1400/ADuM1401/ADuM1402 FEATURES GENERAL DESCRIPTION 1 Qualified for automotive applications The ADuM1400/ADuM1401/ADuM1402 are quad-channel Low power operation digital isolators based on Analog Devices, Inc., iCoupler 5 V operation technology. Combining high speed CMOS and monolithic air 1.0 mA per channel maximum at 0 Mbps to 2 Mbps core transformer technology, these isolation components provide 3.5 mA per channel maximum at 10 Mbps outstanding performance characteristics superior to alternatives, 31 mA per channel maximum at 90 Mbps such as optocoupler devices. 3 V operation By avoiding the use of LEDs and photodiodes, iCoupler devices 0.7 mA per channel maximum at 0 Mbps to 2 Mbps remove the design difficulties commonly associated with opto- 2.1 mA per channel maximum at 10 Mbps couplers. The typical optocoupler concerns regarding uncertain 20 mA per channel maximum at 90 Mbps current transfer ratios, nonlinear transfer functions, and Bidirectional communication temperature and lifetime effects are eliminated with the simple 3 V/5 V level translation iCoupler digital interfaces and stable performance characteristics. High temperature operation: 125C The need for external drivers and other discrete components is High data rate: dc to 90 Mbps (NRZ) eliminated with these iCoupler products. Furthermore, iCoupler Precise timing characteristics devices consume one tenth to one sixth of the power of 2 ns maximum pulse width distortion optocouplers at comparable signal data rates. 2 ns maximum channel-to-channel matching High common-mode transient immunity: >25 kV/s The ADuM1400/ADuM1401/ADuM1402 isolators provide four Output enable function independent isolation channels in a variety of channel configu- 16-lead SOIC wide body package rations and data rates (see the Ordering Guide). All models RoHS-compliant models available operate with the supply voltage on either side ranging from Safety and regulatory approvals 2.7 V to 5.5 V, providing compatibility with lower voltage UL recognition: 2500 V rms for 1 minute per UL 1577 systems as well as enabling a voltage translation functionality CSA Component Acceptance Notice 5A across the isolation barrier. In addition, the ADuM1400/ VDE Certificate of Conformity ADuM1401/ADuM1402 provide low pulse width distortion DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 (<2 ns for CRW grade) and tight channel-to-channel matching V = 560 V peak IORM (<2 ns for CRW grade). Unlike other optocoupler alternatives, the TV approval: IEC/EN/UL/CSA 61010-1 ADuM1400/ADuM1401/ADuM1402 isolators have a patented refresh feature that ensures dc correctness in the absence of input APPLICATIONS logic transitions and when power is not applied to one of the General-purpose multichannel isolation supplies.
