For my senior design project I'm using this ADC (HMCAD1511)
https://www.analog.com/media/en/technical-documentation/data-sheets/hmcad1511.pdf
I'm only using one of its four analog inputs - what should I do with the unused analog input pins?
Is it best to just ground them?
Lastly the same question but more generally for unused digital input and output pins, what should normally be done with them? (I'm guessing there isn't a catch all solution and that it often depends)
