Gain error is based on the ADC only (with a fixed 2.0 V external reference).
Measured at maximum clock rate, f
Includes internal voltage reference error.
Input capacitance refers to the effective capacitance between one differential input pin and AGND. Refer to Figure 7 for the equivalent analog input structure.
Input bias current is due to the input looking like a resistor that is dependent on the clock rate.
Measured with dc input at maximum clock rate.
