Specifications subject to change without notice.
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, f
Input capacitance refers to the effective capacitance between one differential input pin and AGND. Refer to Figure 2 for the equivalent analog input structure.
Measured with dc input at maximum clock rate.
Standby power is measured with a dc input, the CLK pin inactive (i.e., set to AVDD or AGND).
