Tool/software:
The ADC is described as fully differential, but the common-mode range is tightly specified near Vref/2.
Will it report, say, 1 volt input if AINP is +1.7 and AINM is +0.7? In other words, does it digitize the difference between the inputs even if the common-mode is not Vref/2?
What happens in the case above?
I have a 3.3 volt reference and a differential signal, both inputs always between 0 and Vref, common-mode typically 1.2v, but don't want to add another amplifier.
Thanks
