As title, can we leave ADS112C04's REFP and REFN pins open (floating) when using internal reference?

Hi Wayne,

The short answer is yes, the reference pins can be left floating if not used. There is a section in the ADS112C04 datasheet that discusses Unused Inputs and Outputs in section 9.1.3 on page 47.

Best regards,

Bob B
