is there any optocoupler ,which can be used to isolate the analog signals?
the voltage varies from 0 to 5 v.
also the optocoupler should be easily available

Hi --BawA--
And the frequency and accuracy of your analog signal ?
Anyway , I highly recommend you IL300 . with a simple trick you can use it to handle your purpose .

hi goldsmith , actually i have made a dc dc converter using pushpull topology its 12vdc to 311vdc . for feedback i have implemented voltage divider method, i want to isolate the sg3525 from high voltage , so i am planning to use some optocoupler ,so can you suggest me any optocoupler which suits my application ?

Hi --BawA--

Then it's much simpler ! use PC817 and TL431 for your feedback path , if you're not familiar with this section i can give you the proper schematic for this section ?
