3.2.2.3 DAC Quick-Start Page

This page is divided in to four tabs:

Basic DAC

,

Margining

,

Functions

, and

Alarms

. The following subsections

describe each tab.

3.2.2.3.1 Basic DAC Tab

The

Basic DAC

quick-start tab is shown in

provides an interface to quickly power up, select the

reference and output span, and program the output voltage (decimal) for the DAC53701. The DAC53701 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.

Figure 3-7. DAC Quick-Start Page: Basic DAC Tab

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 GPI pin programming has not been provided in this version of the software, although the EVM hardware has
options for providing signals to DAC53701 through header J2
