LINEARITY

Linearity refers to how well a transducer’s output follows

the equation: V

= V + sensitivity x P over the operating

off

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.

DEVIATION

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

MPX2700A 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 Characteris-

tics.

Sensor Die in Its Basic Package (Not to Scale)

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 harsh

environments, while allowing the pressure signal to be

transmitted to the silicon diaphragm. MPX2700A 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.
