    Hi all,

    I'm using PIC18F45K22 to do A/D conversion of signal from INA125. I want to set external VRef +/- on PIC to be equal to the precision voltage reference of INA125.
    Can I connect it directly and do I need to pay attention to PIC VRef+/- input imedance?

    Kind regards

    You can just connect them directly together no worries.
