2.2.2 Power Configurations and Jumper Settings

The DAC63204EVM provides electrical connections to the device supply pins. The connections are shown in Table 2-1.

Table 2-1 DAC63204EVM Power Supply Inputs
DAC63204EVM 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 DAC63204EVM are crucial to the proper operation of the EVM. Table 2-2 provides the details of the configurable jumper settings on the EVM. The DAC63204EVM pin numbers are defined in Figure 4-1.
Table 2-2 DAC63204EVM Jumper Settings
Jumper Default Position Available Option Description
J3 Closed: 5-V USB supply connected to DAC VDD Open: 5-V USB supply disconnected from DAC VDD 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

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.

GPIO2 from the onboard controller is connected to the DAC GPIO pin of the DACx3204. 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.
