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. See Figure 8 for the equivalent analog input structure.

3 The maximum limit applies to the combination of IAVDD and IDVDD currents.

4 Standby power is measured with a dc input and with the CLK pins (CLK+, CLK

−) inactive (set to AVDD or AGND).
