Application Note AN1646.
Figure 2 illustrates the 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 sen-
sor diaphragm. The MPX4200A series pressure sensor
operating characteristics, and internal reliability and quali-
fication 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
interfacing the output of the integrated sensor to the A/D in-
put of a microprocessor or microcontroller. Proper decoup-
ling 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 temperature range of 0° to
85°C. The output will saturate outside of the specified pres-
sure range.
