Figure 2. Output vs. Pressure Differential  
Figure 2 shows the output characteristics of the MPX2053/  
MPXV2053G 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 Characteristics.

Figure 3. Unibody Package: Cross Sectional Diagram (Not to Scale)  
Figure 3 illustrates the differential/gauge die 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.  
The MPX2053/MPXV2053G series pressure sensor  
operating characteristics 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 regarding media compatibility in your  
application.

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 4) 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.

Pressure (% Full Scale)  
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.  
Freescale’s specified pressure sensor linearities are based  
on the end point straight line method measured at the  
midrange pressure.
