DAC SLOPING STOPBAND FILTER
Two DAC filter types are available, selected by the register bit DAC_SB_FILT. When operating at
lower sample rates (e.g. during voice communication) it is recommended that the sloping stopband
filter type is selected (DAC_SB_FILT=1) to reduce out-of-band noise which can be audible at low
DAC sample rates. See “Digital Filter Characteristics” for details of DAC filter characteristics.

DAC OVERSAMPLING RATIO (OSR)
The DAC oversampling rate is programmable to allow power consumption versus audio performance
trade-offs. The default oversampling rate is low for reduced power consumption; using the higher
OSR setting improves the DAC signal-to-noise performance.
