Gain error and gain temperature coefficients are based on the ADC only, with a fixed 1.0 V external reference and a 2 V p-p differential analog input.
Input capacitance refers to the effective capacitance between one differential input pin and AGND. Refer to Figure 4 for the equivalent analog input structure.
