Measured with a 10 MHz input frequency at rated sample rate, full-scale sine wave, with approximately 5 pF loading on each output bit.
Input capacitance refers to the effective capacitance between one differential input pin and AGND.
Standby power is measured with a dc input, the CLK pin inactive (set to AVDD or AGND).
