3 On-chip Temperature Compensation and Calibration
Figure 5 shows the sensor output signal relative to pressure input. Typical, minimum, and maximum output curves are shown for
operation over a temperature range of 0 to 85 °C using the decoupling circuit shown in Figure 7. The output will saturate outside
of the specified pressure range.
Figure 6 illustrates both the Differential/Gauge and the Absolute Sensing Chip in the basic chip carrier. 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 characteristics, 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 7 shows the recommended decoupling circuit for interfacing the output of the integrated sensor to the A/D input of a
microprocessor or microcontroller. Proper decoupling of the power supply is recommended.

4 Package Information
4.1 Pressure (P1)/Gauge (P2) side identification table
NXP designates the two sides of the pressure sensor as the Pressure (P1) side and the Gauge (P2) side. The Pressure (P1) side
is the side containing fluoro-silicone gel which protects the die from harsh media. The MPX pressure sensor is designed to
operate with positive differential pressure applied, P1 > P2.
The Pressure (P1) side may be identified by using the table below.
4.2 Minimum recommended footprint for surface mounted applications
Surface mount board layout is a critical portion of the total design. The footprint for the surface mount packages must be the
correct size to ensure proper solder connection interface between the board and the package. With the correct footprint, the
packages will self align when subjected to a solder reflow process. It is always recommended to design boards with a solder mask
layer to avoid bridging and shorting between solder
