Pressure
On-Chip Temperature Compensation and Calibration
Figure 2 shows the output characteristics of the MPX2102
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. Cross Sectional Diagrams (Not to Scale)
Figure 3 illustrates the absolute sensing configuration
(right) and 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.
The MPX2102 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.
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.
