18f8722 vref pin +

Post by Roy Johnston »

I want to use the vref+ pin as a reference for my analogue inputs.
I noticed on this chip it has a Vref - pin as well.
the question is would the vref - pin have any influence on my analogue inputs if I am using the vref+.
basically I don't want the vref - feature at all.

thank for any advise.

Hi Roy,
No, the Vref- will not be used as the registers set within PIC_CAL_ADC.c will only be set for Vref+ when that option is selected.
If Vref- was ever required then PIC_CAL_ADC.c will require modification.
