SLAU841A October 2020 – October 2022 DAC43701 , DAC43701-Q1 , DAC53701 , DAC53701-Q1
The DAC53701EVM provides electrical connections to the device supply pins. Table 2-1 shows the connections.
DAC53701EVM 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 DAC53701EVM are crucial to the proper operation of the EVM. Table 2-2 provides the details of the configurable jumper settings on the EVM.
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: I2C disabled | I2C enable |
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 GPI pin of the DACx3701. This input can be controlled through the graphical user interface (GUI) using the controls for GPIO2.
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.
