NOTES

1Oversampling disabled. Static DAC performance will be improved with increased oversampling ratios.

2DNL measures the deviation of the actual DAC output voltage step from the ideal. For +ve DNL, the actual step value lies above the ideal step value; for –ve DNL,

the actual step value lies below the ideal step value.

3Value in brackets for VDD_IO = 2.375 V–2.75 V.

4External current required to overdrive internal VREF.

5IDD, the circuit current, is the continuous current required to drive the digital core.

6Guaranteed maximum by characterization.

7IAA is the total current required to supply all DACs including the VREF circuitry and the PLL circuitry.

8All DACs on.
