Equation 6-2 shows an example of calculating the
expected number of output code with various PGA gain
settings for Type K thermocouple output.

FIGURE 6-7:
Example of Pressure and Temperature Measurement.
Figure 6-7 shows an example of measuring both
pressure and temperature. The pressure is measured
by using NPP 301 (manufactured by GE NovaSensor),
and temperature is measured by a thermistor.
The pressure sensor output is 20 mV/V. This gives
100 mV of full scale output for VDD of 5V (sensor
excitation voltage). Equation 6-3 shows an example of
calculating the number of output code for the full scale
output of the NPP301.
