4.1 AVDD and DVDD Inputs: J2 and J3

There are two screw terminals that allow external supplies to be connected. The J2 screw terminal allows the user to externally provide power to AVDD and the screw terminal J3 allows the user to externally provide power to DVDD. The AVDD supply must be between 3 VDC and 5.5 VDC and the DVDD supply must be between 3 VDC and 5 VDC. Figure 4-1 shows the input power scheme.
