Gain error and gain temperature coefficient are based on the ADC only (with a fixed 1.0 V external reference).
Measured at maximum clock rate with a low frequency sine wave input and approximately 5 pF loading on each output bit.
Input capacitance refers to the effective capacitance between one differential input pin and AVSS. Refer to Figure
Measured with dc input at maximum clock rate.
Standby power is measured with the CLK_A and CLK_B pins inactive (that is, set to AVDD or AGND).
