I need to trace the AC line voltage with ADC in a dspic.
I want to use it without transformer - that is with optocoupler.
I need to transfer AC to otherside (DC side) centered at +2.5 volts (0-5V) -so AC opto is needed with linearity.
I located data sheets for IL256,HCPL354 (AC optos). None of them says 'liner'.
But I have located data sheets like HCNR200 which says 'linear', but not AC.
How can I tackle this situation?
What about two linear DC optos like a voltage divider in the DC side?
Thanks
