POWER SUPPLY NOTES
Two different strategies can be used to minimize power supply noise/interference.
a) Recommended strategy: keep analog and digital power supply rails separate. This requires to use two sets
Figure 10.
b) Low cost strategy: tie analog and digital power supplies together as close as possible to GND and VCC pins.

of capacitors, one from AVCC to AGND and the other from DVCC to DGND.
This allows to use only one set of capacitors between VCC and GND.
