Schematics and Bill of Materials

The Reference Source control selects between the ADS8028 internal voltage reference (INT) and an

external voltage reference source (EXT). Selecting EXT disables the internal voltage reference and allows

the user to specify the applied reference voltage in the Reference Voltage indicator to display the correct

voltage output values.

The Temperature Averaging control configures the ADS8028 to average eight temperature

measurements.

The Read Temp button returns the output of the internal ADS8028 temperature sensor reading. The

output code is displayed in the Internal Temperature Data indicator and the corresponding temperature

value in degrees Celsius is displayed in the Internal Temperature indicator.

4.4 About Tab

The About tab provides information on the EVM hardware and software versions.

The plug-in version is the software version of the ADCPro plug-in. The firmware version is the firmware

version loaded and running on the processor.
