ADUM1402CRWZ-RL Description The ADuM1400/ADuM1401/ADuM14021 are quad-channel digital isolators based on Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocoupler devices. 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 ADUM1402CRWZ-RL Features Qualified for automotive applications Bidirectional communication 3 V/5 V level translation High temperature operation: 125°C High data rate: dc to 90 Mbps (NRZ) High common-mode transient immunity: >25 kV/μs Output enable function 16-lead SOIC wide body package RoHS-compliant models available ADUM1402CRWZ-RL Applications General-purpose multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceivers Industrial field bus isolation Automotive systems
