Switching Power Supply
Optionally, the ADC on the board can be configured to use the
ADP2114
DRVDD and AVDD rails of the ADC. To configure the board
to operate from the ADP2114, the following changes must be
incorporated (see the Evaluation Board Schematics and Artwork
and the Bill of Materials sections for specific recommendations
for part values):
1.
2.
Install R204 and R221 to enable the ADP2114.
Install R216 and R218.

Making these changes enables the switching converter to power
the ADC. Using the switching converter as the ADC power
source is more efficient than using the default LDOs.
Install L201 and L202.
Remove JP201 and JP203.
Remove jumpers from across Pin 1 and Pin 2 on P107 and
P108, respectively.
Place jumpers across Pin 1 and Pin 2 of P106 and P109,
respectively.
