The second tab in the spreadsheet allows the user to enter the temperature range and room temperature
diode voltage (light blue areas). The spreadsheet calculates the diode voltages and displays the results in
the yellow areas. Note that the Temp ADC area is specific to the PGA309 sensor signal conditioning chip.
The Temp ADC values will be used in the computation of the Counts for the temp ADC. The next several
pages will show how the diode voltages are used to program the sensor emulator.
