ADUM3400ARWZ

数字隔离器 Quad-CH Digital EH System-Level ESD

Quad-Channel, Digital Isolators,  Enhanced System-Level ESD Reliability

GENERAL DESCRIPTION ADUM3400ARWZ

The ADuM3400/ADuM3401/ADuM34021 are 4-channel digital isolators based on the 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.

iCoupler devices remove the design difficulties commonly  associated with optocouplers. 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 the  power of optocouplers at comparable signal data rates.
