1
Gain errors and gain temperature coefficients are based on the ADC only (with a fixed 1.0 V external reference).
2
Measured at maximum clock rate, low input frequency, 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.
4
Measured with dc input at maximum clock rate.
5
Standby power is measured with a dc input, the CLK pin inactive (that is, set to AVDD or AGND).
