The MPXV7025 series piezoresistive transducer is a state-of-the-art
monolithic silicon pressure sensor designed for a wide range of applications,
but particularly those employing a microcontroller or microprocessor with A/D
inputs. This patented, single element transducer combines advanced
micromachining techniques, thin-film metallization, and bipolar processing to
provide an accurate, high level analog output signal that is proportional to the
applied pressure.

1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2. Device is ratiometric within this specified excitation range.
3. Offset (Voff) is defined as the output voltage at the minimum rated pressure.
4. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure.
5. Full Scale Span (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
minimum rated pressure.
6. Response Time is defined as the time for the incremental change in the output to go from 10% to 90% of its final value when subjected to
a specified step change in pressure.
7. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized.
8. Offset Stability is the product's output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

On-chip Temperature Compensation and Calibration
The MPXV7025 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.

0 to 85C using the decoupling circuit shown in Figure 3. The
output will saturate outside of the specified pressure range.
Figure 3 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.

PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE
Freescale designates the two sides of the pressure sensor
as the Pressure (P1) side and the Vacuum (P2) side. The
Pressure (P1) side is the side containing fluorosilicone gel
which protects the die from harsh media. The pressure
sensor is designed to operate with positive differential
pressure applied, P1 > P2.
The Pressure (P1) side may be identified by using the
following table:

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 pads.
