Static DAC performance will be improved 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 Value in brackets for 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. |
