1 Gain error and gain temperature coefficient are based on the ADC only (with a fixed 1.0 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 Input capacitance refers to the effective capacitance between one differential input pin and AGND. Refer to Figure 4 for the equivalent analog input structure.
4 Measured with dc input at maximum clock rate.
