OPEDA[3:0] DAC Operation control
These bits control the DAC operation mode. In operation disable mode, the DAC output is cut off
from DIN with a fade-out sequence, and the internal DAC data is reset. DAC output is forced into
VCOMDA if PSMDA = 1, or DAC output is forced into AGNDDA and goes into a power-down
state if PSMDA = 0. For normal operating mode, a fade-in sequence is applied on the DAC
output in resume process. The serial mode control is effective during operation disable mode. A
wait time greater than tDACDLY2 is required for the status change because of power-save control
turning on/off.
Default value: 0000.

DAC Digital filter roll-off control
The FLT[3:0] bits allow users to select the digital filter roll-off that is best suited to their
applications. Sharp and Slow filter roll-off selections are available. The filter responses for these
selections are shown in the Typical Characteristics section of this data sheet.
Default value: 0000.
