    Hello,

    When using the device with two single-ended channel configuration, the unused input can be connected to ground. But, i would greatly suggest, if this is your case, to use the device in "Single-Channel, Single-Ended Configuration with Remote Ground Sensing"

    The hardware would not need to change if AIN0 is the input signal and AIN1 is the unused input connected to ground. this will help to eliminate any movement in the ground and provide slightly more accurate measurements. It can also help if the source is far away from the ADC 

    Regards
