2.6.1 Power Consumption Testing

Many of the DAC8N devices feature low power consumption. By default, the communication voltage level shifter and the onboard 2.5V reference run off the VDD voltage. The DAC8N-DGK-EVM has the functionality to isolate the DUT VDD for testing power consumption. To isolate the DUT, remove R16 and apply VDD power to TP14 and a ground test point. Apply board power through J3 or J1 as normal to power the rest of the board.
