I have a question about differential input PulSAR ADC.
These ADC has the specification about Common-Mode Input Range.
In AD7682, Vref/2 + 0.1 V (max).
What behavior does ADC do if the input signal is different from the specification of Common-Mode Input Range?
In my system, when the sine wave was input and tested, the value to which the digital output sometimes jumped was observed.
I am understood not to operate normally because this is a usage different from the specification.
Why does ADC do such behavior when a usage different from the specification of Common-Mode Input Range?
I want to know the mechanism.
