Motorola Sensor Device Data
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 or (2) a least
squares best line fit (see Figure 3). 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 MPX2700
series at 25
°
C. The output is directly proportional to the dif-
ferential 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 Characteris-
tics.

Figure 4 shows the cross section of the Motorola MPX
pressure sensor die in the chip carrier package. 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. MPX2700 series
pressure sensor operating characteristics and internal reli-
ability 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.
