1 Oversampling disabled. Static DAC performance improves with increased oversampling ratios.
2 DNL 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.
3 For values in brackets, VDD_IO = 2.375 V to 2.75 V.
4 External current required to overdrive internal VREF.
5 IDD, the circuit current, is the continuous current required to drive the digital core.
6 Guaranteed maximum by characterization.
7 All DACs on.
8 IAA is the total current required to supply all DACs, including the VREF circuitry and the PLL circuitry.
