-
Power The ground reference for the analog circuits (ADC, Analog
97
Comparators, etc.). These are separated from GND to
minimize the electrical noise contained on VDD from affecting
the analog functions.

LDO
7
-
Power Low drop-out regulator output voltage. This pin requires an
external capacitor between the pin and GND of 1 µF or
greater. The LDO pin must also be connected to the VDD25
pins at the board level in addition to the decoupling
capacitor(s).
