2.2.3.1 Power Configuration

The default configuration of the AFE882H1EVM allows the board to be powered from the USB while using an external source for the ±15-V supplies. Jumper J26 connects power from the 3p3V line to the PVDD pins of the device, and jumper J27 connects power to the IOVDD pins of the device. To use external power supplies, remove the jumpers in J26 and J27 and connect the supplies to banana jacks J22 and J24 for connections to PVDD and IOVDD.
