ADC Vref+ on PIC16F88

Hi all,

Can i connect the pic's :
Vref+ = 5V (Vcc)
VRef- = 12V
Measure at 12.5V

and get the reading as 0.5V = 102.4 unit after the conversion of 10 bits resolution????

By the way, what is the maximum Vref-, Vref+ and the voltage the pic can measure?

Hi,

Smoke Guaranteed !!!

ALL voltages on every pin must be inside the VDD-VCC range ...
