low cost isolated voltage measurement
(OP)
What solutions are available for high voltage isolated measurement upto 600V which will be interfaced to an adc or mcu, also low cost?

RE: low cost isolated voltage measurement
There are also dual optocouplers that can be used in linear applications and make around one percent untrimmed accuracy possible. And then, there is the PWM technique or V/f and transmission via a small HF transformer or opto coupler.
And, of course, the Burr Brown piezoelectric isolator can also be used in circuits where the du/dt isn't too high.
