(1)

The INL is measured at the output of the DAC (accessible at an external pin during bypass mode).

(2)

The DNL is measured at the output of the DAC (accessible at an external pin during bypass mode).

(3)

Assuming a capacitor of 0.1

µF at the tv_ref node.

(4)

The analog supply current Ivdda is directly proportional to the full-scale output current IFS and is insensitive to fCLK

(5)

The digital supply current IVDD is dependent on the digital input waveform, the DAC update rate fCLK, and the digital supply VDD.

(6)

The peak digital supply current occurs at full-scale transition for duration less than 1 ns.
