I have question concerning ADS41B29 maximum voltage rating for the analog inputs. According to the data sheet absolute maximum rating for INP and INM is “Minimum (1.9, AVDD + 0.3V)”. How to understand this? Analog buffer of this ADC is powered from AVDD_BUF 3.3V. Shouldn't the maximum rating be equal to AVDD_BUF + 0.3V? I need to know the answer to design correct input protection circuit.
