Hello Guys!
The maximum differetial input range is 4,8V with a Gain of 1 and a reference of 2,4V, but what is the maximum voltage a single analog input of the ADS1298 can handle without the risk of getting damaged?
kind regards
Sebastian

Hi Sebastian,
The maximum voltage allowed on each analog input is listed in the Absolute Maximum Ratings table on page 2 of the datasheet. This rating is provided with respect to the power supplies used for the device.
Also, just to clarify, the maximum differential input to the ADC is +/- VREF, not 2*VREF. If the absolute value of the differential input is greater than the reference voltage, the ADC will output a code that corresponds to +/- full-scale. Please refer to the Data Format section of the datasheet to see how the output codes map to the full-scale input range.
Best Regards,
