数字隔离器 Digital Quad-CH

Quad-Channel Digital Isolators

GENERAL DESCRIPTION ADUM1400BRWZ

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.

APPLICATIONS ADUM1400BRWZ
