Figure 3. Recommended power supply decoupling
and output filtering.
For additional output filtering, please refer to
Application Note AN1646.
Figure 2 illustrates the differential/gauge pressure sensing
chip in the basic chip carrier (Case 867). A fluorosilicone gel
isolates the die surface and wire bonds from the environ-
ment, while allowing the pressure signal to be transmitted to
the sensor diaphragm.
The MPX4250D series pressure sensor operating charac-
teristics 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 the recommended decoupling circuit for in-
terfacing the output of the integrated sensor to the A/D input
of a microprocessor or microcontroller.
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 using the decoupling circuit shown in Figure 3. The
output will saturate outside of the specified pressure range.
