1 Measured with a low input frequency, full-scale sine wave, with approximately 5 pF loading on each output bit.
2 Input capacitance refers to the effective capacitance between one differential input pin and AGND. Refer to Figure x for the equivalent analog input structure.
3 Standby power is measured with a dc input, the CLK pin inactive (set to AVDD or AGND).
