1
With a 1.0 V internal reference.
2
Measured at the 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. See Figure 4 for the equivalent analog input structure.
4
Measured at ac specification conditions without output drivers.
5
Standby power is measured with a dc input, CLK pin inactive (that is, set to AVDD or AGND).
