ADUM1200BRZ

数字隔离器 Dual-Channel Digital Isolators

GENERAL DESCRIPTION ADUM1200BRZ

The ADuM1200/ADuM12011 are dual-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technologies, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocouplers.

By avoiding the use of LEDs and photodiodes, iCoupler devices  remove the design difficulties commonly associated with optocouplers.
