Temperature Compensated and
Calibrated
The MPVZ5010G series piezoresistive transducers are state-of-the-art
monolithic silicon pressure sensors designed for the appliance, consumer,
healthcare, industrial and automotive market. The analog output can be read
directly into the A/D input of Freescale microcontrollers. This 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. The axial port has been modified to
accommodate industrial grade tubing.

Sensitivity
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. Accuracy (error budget) consists of the following:
• Linearity:
Output deviation from a straight line relationship with pressure over the specified pressure range.
• Temperature Hysteresis: Output deviation at any temperature within the operating temperature range, after the temperature is cycled to
and from the minimum or maximum operating temperature points, with zero differential pressure applied.
• Pressure Hysteresis:
Output deviation at any pressure within the specified range, when this pressure is cycled to and from the
minimum or maximum rated pressure, at 25°C.
• TcSpan:
Output deviation over the temperature range of 0° to 85°C, relative to 25°C.
• TcOffset:
Output deviation with minimum rated pressure applied, over the temperature range of 0° to 85°C, relative to 25°C.
• Variation from Nominal: The variation from nominal values, for Offset or Full Scale Span, as a percent of VFSS, at 25°C.
7. 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.
8. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized.
9. 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, CALIBRATION AND SIGNAL CONDITIONING
The performance over temperature is achieved by
integrating the shear-stress strain gauge, temperature
compensation, calibration and signal conditioning circuitry
onto a single monolithic chip.
Figure 2 illustrates the Differential or Gauge configuration
in the basic chip carrier (Case 482). A gel die coat isolates the
die surface and wire bonds from the environment, while
allowing the pressure signal to be transmitted to the sensor
diaphragm.
The MPVZ5010G series pressure sensor operating
characteristics, internal reliability and qualification tests are
based on use of dry air as the pressure media. Media, other
Fluoro Silicone
Gel Die Coat
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
interfacing the integrated sensor to the A/D input of a
microprocessor or microcontroller. Proper decoupling of the
power supply is recommended.
Figure 4 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 3. The
output will saturate outside of the specified pressure range.

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 a gel die coat which
protects the die from harsh media. The MPX pressure sensor
Part Number
is designed to operate with positive differential pressure
applied, P1 > P2.
The Pressure (P1) side may be identified by using the

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.
