ON Semiconductor NCID9211 ceramic digital isolator
The NCID9211 is part of a family of galvanically digital isolators that use ON Semiconductor's patented off-chip capacitor isolation technology
The NCID9211 is part of a family of galvanically digital isolators that use ON Semiconductor's patented off-chip capacitor isolation technology. These isolators support digital communication between systems without conducting ground loops or hazardous voltages.
Their capactive ceramic substrate construction offers ~25 times the thickness of thin film on-chip capacitors and coreless transformers, resulting in electrical performance benefits traditionally offered by optocouplers but exceeding optocouplers in speed, common mode transient immunity as well as temperature and lifetime performance.
