For my project, I am using the ADE7880. Everything works as I expected but I just have a little question.
In my application, in some case the sensors will be plugged while there is no alimentation in the ADE7880's VDD.
So there will be +-500mV on the ADE7880's ADC while the ADE7880 doesn't have any alimentation. Is it a problem (are there some clamp diodes which could feed the ADE7880 with the ADC's signals) ?
Thanks for your help,
