    I need to design a multi-channel isolated 15v /ch voltage monitor. Each ch will be isolating an SPI bus up to 1500vdc working voltage. This will be used to allow voltage monitoring of individual 12v car batteries in a series stack of 100. Any way to isolate with that much common mode?

        Dont know? which will have the best results? I dont have a schematic or block yet.The layout is up to me.  Its pretty straightforward though, I just need to withstand a 1500vDC working voltage continuously.  The board will be FR-04. I would like an isolator with a power supply included like the adum6402; thought the spec for those was 848v or so.
