Hi,
I'm using PIC18F4520 for my project. my input for ADC is 200mV to 1.2V.
now i want to give vref to my microcontroller. It has to pin RA3/AN3/
VREF+ and RA2/AN2/VREF-/CVREF pins.
So how do i give Vref? should i apply 1.5v to only VREF+ and keep open VREF- or should i ground the Vref- pin??
Please help.
Rgds,
Sid
