Motorola Sensor Device Data
ON–CHIP TEMPERATURE COMPENSATION and CALIBRATION
Figure 2 shows the output characteristics of the MPXT2010
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
small and are shown under Operating Characteristics.
Figure 3 illustrates the differential/gauge die in the basic
chip carrier (Case 473). 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 MPXT2010 series pressure sensor operating charac-
teristics, 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 re-
garding 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, or (2) a least
squares best line fit (see Figure 4).
When calculating linearity, Motorola uses the end–point
straight line fit. This method measures the two end and the
mid range pressure points and compares to ideal. This typi-
cally represents the “worst case” error which is often more
desirable for the customers when calculating an error budget
in their designs.
