Motorola Sensor Device Data
LINEARITY
Linearity refers to how well a transducer’s output follows
the equation: V
out
= V
off
+ 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
pressure.

Figure 3 shows the output characteristics of the
MPX2202/MPXV2202G 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 4 illustrates an absolute sensing die (right) and the
differential or 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 MPX2202/MPXV2202G series pressure sensor oper-
ating characteristics and internal reliability and qualification
tests are based on use of dry air as the pressure media. Me-
dia 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.
