Figure 2. Recommended Decoupling Filter for
Sensor to Microprocessor Interface
This surface mount package (Case 471–01) is an absolute
sensing configuration package. A fluorosilicone gel isolates
the die surface and wire bonds from the environment, while
allowing the pressure signal to be transmitted to the silicon
diaphragm. The MPXS4115A series pressure sensor oper-
ating characteristics, 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 perfor-
mance and long–term reliability. Contact the factory for in-
formation regarding media compatibility in your application.
Figure 2 shows the recommended decoupling circuit for in-
terfacing the output of the integrated BAP sensor to the A/D
input of a microprocessor (see Note 10).
Figure 3 shows the sensor output signal relative to pres-
sure input. Typical minimum and maximum output curves are
shown for operation over 0 to 85
°
C temperature range. (Out-
put will saturate outside of the rated pressure range.)
