Input capacitance refers to the effective capacitance between one differential input pin and AGND. See Figure 11 for the equivalent analog input structure.
2
Measured with a 9.7 MHz, full-scale sine wave input, NCO enabled with a frequency of 13 MHz, FIR filter enabled and the f
S
/8 output mix enabled with approximately
5 pF loading on each output bit.

The maximum limit applies to the combination of I
AVDD
and I
DVDD
currents.
4
Standby power is measured with a dc input, the CLK pin inactive (set to AVDD or AGND).
