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

°C using the decoupling circuit shown in Figure 3. The

output will saturate outside of the specified pressure range.
