Oversampling disabled. Static DAC performance improves with increased oversampling ratios.

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.
