This platform is a general-purpose data acquisition system that is used on several different Texas Instruments evaluation modules. The details of its operation are included in a separate document, SBOU058 (available for download at www.ti.com).

  • Page 8: Typical Hardware Connections For Buf18830Evm

    Typical Hardware Connections To set up the BUF18830EVM hardware, connect the two PCBs of the EVM together (that is, the BUF18830 Test Board and USB_DIG_Platform board) via a 25-pin DSUB connector, and apply a power source. The external connections may be the real-world system that the BUF18830 will be incorporated into.

  • Page 9: Connecting External Power To The Evm

    Overview www.ti.com Connecting the Hardware To connect the two PCBs of the BUF18830EVM together, gently push on both sides of the DSUB connectors (as shown in Figure 6). Note that the USB_DIG_Platform board has two DSUB connectors; either may be used. Make sure that the two connectors are completely pushed together; loose connections may cause intermittent operation.

  • Page 10: Connecting The Usb Cable To The Usb_Dig_Platform

    Once power is connected, the USB cable must be connected to the USB_DIG_Platform, as shown in Figure 7. Note that the BUF18830EVM test board and the USB_DIG_Platform board must each be powered on before connecting the USB cable. Typically, the computer will respond with a Found New Hardware, USB Device pop-up dialog.

  • Page 11: Buf18830Evm Default Jumper Settings

    BUF18830EVM. In general, the jumper settings of the USB_DIG_Platform will not need to be changed. You may want to change some of the jumpers on the BUF18830EVM board to match your specific configuration. For example, you may wish to set a specific C address.
  • Page 12 Overview www.ti.com Table 3 summarizes the function of the BUF18830EVM board jumpers. For most applications, Jumpers 1 through 5 are all set to the default positions. Table 3. BUF18830EVM Test Board Jumper Functions Jumper Default Purpose This jumper shorts V and AV to each other.
  • Page 13 BUF18830. BUF18830 Device Placement The BUF18830EVM allows the user two separate locations on the board where the BUF18830 test device can be installed. The U1 location on the BUF18830 test board is a 38-pin QFN test socket that allows the user to evaluate and program many devices very quickly.

    2.3.3 Read DAC Button By pressing the Read DAC button in the BUF18830EVM software, all of the BUF18830 DAC/V registers are read to obtain the respective current register contents. Once the read procedure is complete, all of the corresponding text boxes are updated to show the current values present in the DAC/V registers.

  • Page 19: Auto Write Feature Enabled

    The first method allows for the output voltage to change immediately after the writing to the DAC register. In the BUF18830EVM software, this mode is configured by enabling the Auto Write feature found in the Buffer dropdown menu. In this mode, as an individual channel is written to, the output voltage changes as soon as the user moves to a different text box in the software.
