LINEARITY  
Linearity refers to how well a transducer’s output follows  
LEAST SQUARES FIT  
EXAGGERATED  
PERFORMANCE  
CURVE  
the equation: V  
= V + sensitivity x P over the operating  
out  
off  
pressure range. There are two basic methods for calculating  
nonlinearity: (1) end point straight line fit (see Figure 2) or (2)  
a least squares best line fit. While a least squares fit gives  
the “best case” linearity error (lower numerical value), the  
calculations required are burdensome.

Conversely, an end point fit will give the “worst case” error  
(often more desirable in error budget calculations) and the  
calculations are more straightforward for the user. Motorola’s  
specified pressure sensor linearities are based on the end  
point straight line method measured at the midrange  
pressure.

ON–CHIP TEMPERATURE COMPENSATION and CALIBRATION  
Figure 3 shows the output characteristics of the MPX2100  
series at 25°C. The output is directly proportional to the  
differential pressure and is essentially a straight line.  
The effects of temperature on Full Scale Span and Offset  
are very small and are shown under Operating Characteris-  
tics.

Figure 4. Cross–Sectional Diagrams (Not to Scale)  
Figure 4 illustrates the absolute sensing configuration  
(right) and the differential or gauge configuration in the basic  
chip carrier (Case 344–15). A silicone gel isolates the die  
surface and wire bonds from the environment, while allowing  
the pressure signal to be transmitted to the silicon  
diaphragm.  
The MPX2100 series pressure sensor operating charac-  
teristics and internal reliability and qualification tests are  
based on use of dry air as the pressure media. Media other  
than dry air may have adverse effects on sensor perfor-  
mance and long term reliability. Contact the factory for in-  
formation regarding media compatibility in your application.
