TI recommends connecting a combination of a 10-µF and a 100-nF low-ESR ceramic decoupling capacitor to the DVCC and DVSS pins (see Figure 7-1). Higher-value capacitors may be used but can impact supply rail ramp-up time. Decoupling capacitors must be placed as close as possible to the pins that they decouple (within a few millimeters). Additionally, TI recommends separated grounds with a single-point connection for better noise isolation from digital-to-analog circuits on the board and to achieve high analog accuracy.
