MPXV10GC
SERIES
The MPX10 and MPXV10GC series devices are silicon piezoresistive
pressure sensors providing a very accurate and linear voltage output — directly
proportional to the applied pressure. These standard, low cost, uncompensated
sensors permit manufacturers to design and add their own external temperature
compensation and signal conditioning networks. Compensation techniques are
simplified because of the predictability of Freescale's single element strain gauge
design. Figure 1 shows a schematic of the internal circuitry on the stand-alone
pressure sensor chip.

VOLTAGE OUTPUT VERSUS APPLIED DIFFERENTIAL PRESSURE
The output voltage of the differential or gauge sensor
increases with increasing pressure applied to the pressure
side (P1) relative to the vacuum side (P2). Similarly, output
voltage increases as increasing vacuum is applied to the
vacuum side (P2) relative to the pressure side (P1).

1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2. Device is ratiometric within this specified excitation range. Operating the device above the specified excitation range may induce additional
error due to device self-heating.
3. 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 related pressure.
4. Offset (VOFF) is defined as the output voltage at the minimum rated pressure.
5. Accuracy (error budget) consists of the following:
• Linearity:
Output deviation from a straight line relationship with pressure, using end point method, 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 with the specified range, when this pressure is cycled to and from the minimum
or maximum rated pressure at 25°C.
• TcSpan:
• TcOffset:
Output deviation at full rated pressure over the temperature range of 0 to 85°C, relative to 25°C.
Output deviation with minimum rated pressure applied, over the temperature range of 0 to 85°C, relative
to 25°C.
• TCR:
Z
deviation with minimum rated pressure applied, over the temperature range of -40°C to ±125°C, relative to 25°C.

6. Response Time is defined as the time form 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 is stabilized.
8. Offset stability is the product’s output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

TEMPERATURE COMPENSATION
LINEARITY
Figure 2 shows the typical output characteristics of the
MPX10 and MPXV10GC series over temperature.
Because this strain gauge is an integral part of the silicon
diaphragm, there are no temperature effects due to
differences in the thermal expansion of the strain gauge and
the diaphragm, as are often encountered in bonded strain
gauge pressure sensors. However, the properties of the
strain gauge itself are temperature dependent, requiring that
the device be temperature compensated if it is to be used
over an extensive temperature range.
Linearity refers to how well a transducer’s output follows
the equation: Vout = Voff + sensitivity x P over the operating
pressure range (Figure 3). There are two basic methods for
calculating nonlinearity: 1) end point straight line fit or 2) a
least squares best line fit. While a least squares fit gives the
“best case” linearity error (lower numerical value), the
calculations required are burdensome.
Conversely, an end point fit will give the “worst case” error
(often more desirable in error budget calculations) and the
calculations are more straightforward for the user.
Freescale’s specified pressure sensor linearities are based
on the end point straight line method measured at the
midrange pressure.
Temperature compensation and offset calibration can be
achieved rather simply with additional resistive components,
or by designing your system using the MPX2010D series
sensor.
Several approaches to external temperature
compensation over both –40 to +125°C and 0 to +80°C
ranges are presented in Application Note AN840.

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 silicone gel which
isolates the die from the environment. The Freescale
pressure sensor is designed to operate with positive
differential pressure applied, P1 > P2.
