LINEARITY  
proportional to the pressure applied to the device. This de-  
vice uses a unique transverse voltage diffused semiconduc-  
tor strain gauge which is sensitive to stresses produced in a  
thin silicon diaphragm by the applied pressure.  
Because this strain gauge is an integral part of the silicon  
diaphragm, there are no temperature effects due to differ-  
ences in the thermal expansion of the strain gauge and the  
diaphragm, as are often encountered in bonded strain gauge  
pressure sensors. However, the properties of the strain  
gauge itself are temperature dependent, requiring that the  
device be temperature compensated if it is to be used over  
an extensive temperature range.  
Temperature compensation and offset calibration can be  
achieved rather simply with additional resistive components  
or by designing your system using the MPX2100 series  
sensors.  
Several approaches to external temperature compensa-  
tion over both –40 to +125°C and 0 to +80°C ranges are  
presented in Motorola Applications Note AN840.  
Linearity refers to how well a transducer’s output follows  
the equation: V  
= V + sensitivity x P over the operating  
out  
off  
pressure range (see Figure 2). There are two basic methods  
for calculating nonlinearity: (1) end point straight line fit 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 “worse 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.  
TEMPERATURE COMPENSATION  
Figure 3 shows the typical output characteristics of the  
MPX100 series over temperature.  
The X–ducer piezoresistive pressure sensor element is a  
semiconductor device which gives an electrical output signal

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 helps protect the  
die surface and wire bond from the environment, while allow-  
ing the pressure signal to be transmitted to the silicon dia-  
phragm.  
The MPX100 series pressure sensor operating character-  
istics 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 performance and  
long term reliability. Contact the factory for information re-  
garding media compatibility in your application.
