Some temperature tests



Performed some temperature tests with the partially stuffed ADC Board.
The measured output drift was about 1.5bits/1C.

Method:
No input signal. Checked only output drift with temperature.
Measured temperature with infrared thermometer.  Achieved temperature increase by turning fans off and then by using a desk lamp:

- at ~26C: average measurement on Ch5: 131,649.1 - 4ch_27C_2.xls
- at ~30C: average measurement on Ch5: 131,654.6 - 4ch_30C_1.xls
- at ~31C: average measurement on Ch5: 131,657.2 - 4ch_31C_2.xls
- at ~32C: average measurement on Ch5: 131,658.0 - 4ch_32C_2.xls
- at ~35C: average measurement on Ch5: 131,663.0 - 4ch_35C_1.xls
- at ~58C: average measurement on Ch5: 131,718.3 - 4ch_58C.xls - Here the temperature may off by +/- 3C.
