1

Measured with 1.0 V external reference.

2

Measured with a 10 MHz input frequency at rated sample rate, full-scale sine wave, with approximately 5 pF loading on each output bit.

3

Input capacitance refers to the effective capacitance between one differential input pin and ground.

4

Standby power is measured with a dc input and the CLK+, CLK− active.
