3.2.2.3.1 Basic DPOT Configuration Tab

Figure 3-7 shows the Basic DPOT setup tab that provides an interface to quickly power up, select the reference and output span, and program the output voltage (decimal) for the TPL1401. The TPL1401 comes in Hi-Z power-down mode by default.

Note:

The basic DAC setup for power up, reference selection, and output span selection available in this tab is common to all the tab functions.

The EEPROM PROGRAM button is used to write the latest register settings to the EEPROM. The RELOAD button is used to retrieve the settings stored in the EEPROM. The A0 pin programming has not been provided in this version of the software, although the hardware has options for all four possible configurations.
