    Enable Vref/Vssa

    user_366036678

       Hello,

         

       

         

      Does the Enable Vref/Vssa option in the ADC's Common tab allow us to connect a variable reference in PSoC schematic (rather than allocating a special pin to acquire an external Vref?

          I think this targets removing offset when an external reference, using

             

          a pin, is selected. And I think datasheet accuracy is written around that

             

          assumption. It might be possible to actually use pin as a variable reference,

             

          I would file a CASE to ask if done that keeps datasheet accuracy or that

             

          pin absolutely must be very close to ground level.
