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 with a low frequency sine wave input and approximately 5 pF loading on each output bit.
3
Input capacitance refers to the effective capacitance between one differential input pin and AVSS. Refer to Figure for the equivalent analog input structure. 29
4
Measured with dc input at maximum clock rate.
5
Standby power is measured with the CLK_A and CLK_B pins inactive (that is, set to AVDD or AGND).
