Motorola Sensor Device Data
Figure 2. Cross Sectional Diagram
(Not to Scale)
Figure 2 illustrates an absolute sensing chip in the basic
chip carrier (Case 473). A fluorosilicone gel isolates the die
surface and wire bonds from the environment, while allowing
the pressure signal to be transmitted to the sensor dia-
phragm. The MPXT4100A/4101A/4105A 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.

Figure 3. Decoupling Filter for Sensor to
Microprocessor Interface
Figure 3 shows a typical decoupling circuit for interfacing
the integrated MAP sensor to the A/D input of a microproces-
sor. Proper decoupilng of the power supply is recommended.
Figures 4, 5, and 6 show the sensor output signal relative
to pressure input. Typical, minimum, and maximum output
curves are shown for operation over a temperature range of
0
°
to 85
°
C. (The output will saturate outside of the specified
pressure range.)
