Figure 2 illustrates an absolute sensing chip in the basic
chip carrier (Case 867). 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 MPX4101A 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 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.
Figure 4 shows the sensor output signal relative to pres-
sure 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 pres-
sure range.)
