Figure 3. Recommended power supply decoupling
and output filtering.
For additional output filtering, please refer to
Application Note AN1646.
Figure 2 illustrates the absolute pressure sensing chip in
the basic chip carrier (Case 867). A fluorosilicone gel iso-
lates the die surface and wire bonds from the environment,
while allowing the pressure signal to be transmitted to the
sensor diaphragm.
The MPX4250A/MPXA4250A series pressure sensor op-
erating characteristics and internal reliability and qualifica-
tion tests are based on use of dry air as the pressure
media. Media, other than dry air, may have adverse ef-
fects on sensor performance and long–term reliability.
Contact the factory for information regarding media com-
patibility 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 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.
