2 Mbps DC-Correct Digital Isolator to replace Opto-IsolatorsOpto-isolators offer an inexpensive method of signal isolation, but have some significant limitations, as they tend to degrade with age. This degradation is accelerated by ambient temperature: The longer the devices see a high temperature and the higher the temperature, the faster the degradation of the opto-isolator. The power consumption of IsoLoop devices is independent of the mark space ratio and solely dependent on frequency. This makes for lower power consumption than opto isolators, whose power consumption is heavily dependent on on-state and frequency. More...
