Figure 2. Output versus Pressure Differential

Figure 2 shows the sensor output signal relative to

pressure input. Typical, minimum, and maximum out-

put curves are shown for operation over a temperature

range of 0

° to 85°C using the decoupling circuit shown

in Figure 4. The output will saturate outside of the spe-

cified pressure range.

Figure 3. Cross–Sectional Diagrams

(Not to Scale)

Figure 3 illustrates both the Differential/Gauge and 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 sensor diaphragm.

The MPX5100 series pressure sensor operating char-

acteristics, 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 fac-

tory for information regarding media compatibility in your

application.

Figure 4 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.
