ADUM1201ARZ

Product Summary

The ADUM1201ARZ is a Dual-Channel Digital Isolator based on Analog Devices’ iCoupler technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices. The ADUM1201ARZ provides two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). Both parts operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. The applications of the ADUM1201ARZ are Size-critical multichannel isolation, SPI interface/data converter isolation, RS-232/RS-422/RS-485 transceiver isolation, Digital field bus isolation.
