Hi,
 
I'm planing to use the A2D functionality of the 12F675 to convert 0-10V out to a 0-1024 range, 10 bit A2D conversion. Everything on the 12F675 looks good for that. My question is whether I have to supply a 10V for Vref/GP1/AN1 or is there a way to scale VDD internally such that I can get a 0-10V mapping on the A2D conversion that is performed on AN0?
 
Thanks,
Laura
