Measured with a low input frequency, full-scale sine wave.
Input capacitance refers to the effective capacitance between one differential input pin and its complement.
Input resistance refers to the effective resistance between one differential input pin and its complement.
Standby power is measured with a dc input and the CLK pin inactive (that is, set to AVDD or AGND).
