LINEARITY  
Linearity refers to how well a transducer’s output follows  
the equation: Vout = Voff + sensitivity x P over the operating  
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 pres-  
sure.

Figure 2. Linearity Specification Comparison  
ON–CHIP TEMPERATURE COMPENSATION and CALIBRATION  
Figure 3 shows the minimum, maximum and typical output  
characteristics of the MPX2050 series at 25°C. The output is  
directly proportional to the differential pressure and is essen-  
tially a straight line.  
The effects of temperature on Full–Scale Span and Offset  
are very small and are shown under Operating Characteris-  
tics.

Figure 3. Output versus Pressure Differential  
Figure 4. Cross–Sectional Diagram (not to scale)  
Figure 4 illustrates the differential or gauge configuration  
in the basic chip carrier (Case 344). 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.  
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.
