Measured with 1.0 V external reference.
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 and the CLK active.
