Data Sheet Quad-Channel Digital Isolators ADuM1400/ADuM1401/ADuM1402 FEATURES GENERAL DESCRIPTION Qualified for automotive applications The ADuM1400/ADuM1401/ADuM14021 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 0.7 mA per channel maximum at 0 Mbps to 2 Mbps 2.1 mA per channel maximum at 10 Mbps 20 mA per channel maximum at 90 Mbps Bidirectional communication 3 V/5 V level translation High temperature operation: 125°C High data rate: dc to 90 Mbps (NRZ) Precise timing characteristics 2 ns maximum pulse width distortion By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one tenth to one sixth...
