Linear DC Signal Opto Isolator Jim Keith This simple circuit provides better than 1% accuracy in optically coupling a DC voltage signal. To compensate for the non-linearity of the optical isolator, an identical device is connected in the feedback loop. To further enhance stability, both optical isolators are located inside the same IC.

This linear optocoupler is built with MOC5010 and can be used to isolate a circuit from main grid, audio interface, in medical electronics and many other applications. Because of its high isolation resistance (10 11 Ω), MOC5010 is used in applications where a circuit is powered directly from main power.
