3.2 PVDD Power Supply Options

PVDD pin on U1 is directly connected to J13 which can be used to measure current consumption on TAS2020. Banana jack J13 can be connected to barrel-jack J21 by shorting the 2 jumpers on J22. This allows flexible supply options for PVDD to use either banana or barrel-jack supply.
