In ADS54j40 datasheet analog input section, it states that the each input pin must be between VCM + 0.475V and VCM - 0.475V. Can you please let me know if the swing is over +/-0.475V, will it damage the ADC chip??
In the datasheet, it only show the max value for INP. INM within -0.3V and 3V. This is reference to the ground not the differential pins.
In our application, we have a remote sensor and and AC coupled to the ADC. pic as below, can you please help review if that's sufficient protection?
