Would it be possible to change VREF to 8V ?
The Vref supply is a stabilised 5VDC non-variable voltage built into the hardware and cannot be changed. it is intended to be used as a supply for 5VDC sensors which is the standard in the automobile industry.
if you need an 8V supply you'll have to arrange it externally yourself.
Thanks for the info.
