1 Gain error is based on the ADC only (with a fixed 2.0 V external reference).
2 Measured at maximum clock rate, fIN = 2.4 MHz, full-scale sine wave, with approximately 5 pF loading on each output bit.
3 Includes internal voltage reference error.
4 Input capacitance refers to the effective capacitance between one differential input pin and AGND. Refer to Figure 7 for the equivalent analog input structure.
5 Input bias current is due to the input looking like a resistor that is dependent on the clock rate.
6 Measured with dc input at maximum clock rate.
