ADUM3211ARZ

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

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

GENERAL DESCRIPTION ADUM3211ARZ

The ADuM3210/ADuM32111 are dual-channel digital isolators

based on Analog Devices, Inc., iCoupler® technology. Combining

high speed CMOS and monolithic transformer technology, this

isolation component provides outstanding performance characteristics

superior to alternatives such as optocoupler devices.
