ADS1248 unused REFP0,REFN0,REFP1 and REFN1-pins.

Hi

When using the built-in reference, a terminal for REFP1 and REFN1 isn't used. (VREFP0 and VREFN0 aren't also used.)

Please tell me processing of unused pin.

Best regards

  • Cafain,


    For the unused reference pins, I would just leave them floating. You can think of these inputs as part of an unselected multiplexer. As long as nothing actively forces these pins above AVDD or below AVSS it should be fine.
