2.2.2 Power Configurations and Jumper Settings

The DAC63004WCSP-EVM provides electrical connections to the device supply pins. Table 2-1 shows the connections.

Table 2-1 DAC63004WCSP-EVM Power Supply Inputs

DAC63004WCSP-EVM Connector	Supply Name	Voltage Range
J2.1	VDD	1.8 V to 5.5 V (5 V available from the USB); remove J3 if applying an external VDD to the DAC.
J1.1	GND	0 V

The jumper settings on the DAC63004WCSP-EVM are crucial to the proper operation of the EVM. Table 2-2 provides the details of the configurable jumper settings on the EVM.

Table 2-2 DAC63004WCSP-EVM Jumper Settings

Jumper	Default Position	Available Option	Description
J3	Closed: 5-V USB supply connected to EVM VDD supply	Open: 5-V USB supply disconnected from EVM VDD supply	External or onboard VDD selection
J5	2-3: I²C enabled	1-2: SPI enabled	I²C or SPI selection
J6	Closed: GPIOs enabled	Open: GPIOs disabled	Controller GPIO enable
J7	Closed: EVM VDD supply connected to DAC VDD	Open: EVM VDD supply disconnected from DAC VDD	Supply selection for theDACx3004W

If an external supply is applied to the DAC VDD pin, remove jumper J3 to disconnect the 5-V USB supply from the DAC VDD pin.

J7 can be used to measure the supply current for the DACx3004W. Place jumper J7 to connect the EVM supply to the DACx3004W. Remove jumper J7 and place a current meter between the J7 header pins to measure the current consumed by the ultra-low power DACx3004W.

GPIO2 from the onboard controller is connected to the DAC GPIO pin of the DACx3004W. This input can be controlled through the graphical user interface (GUI) using the controls for GPIO2. If DAC GPIO is configured as an output, remove J6 to disable the GPIOs from the onboard controller.

GPIO3 from the onboard controller is broken out to J1, pin 8 and is controlled through the GUI using the controls for GPIO3.

To enable the GPIO pins, close jumper J6. To disable the GPIO pins, remove jumper J6.
