The MPX53/MPXV53GC series silicon piezoresistive pressure sensors provide 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 compensating and signal conditioning networks.
Compensation techniques are simplified because of the predictability of Motorola’s single
element strain gauge design.

VOLTAGE OUTPUT versus APPLIED DIFFERENTIAL PRESSURE
The differential voltage output of the sensor is directly proportional to the differential
pressure applied.
MPX53DP
CASE 344C
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).

NOTES:
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 (V
) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
FSS
minimum rated pressure.
4. Offset (V ) is defined as the output voltage at the minimum rated pressure.
off
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 within 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 –ā 40°C to +125°C,
in
relative to 25°C.
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. Offset stability is the product’s output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

TEMPERATURE COMPENSATION
Figure 2 shows the typical output characteristics of the
MPX53/MPXV53GC series over temperature.
or by designing your system using the MPX2053 series
sensors.
Several approaches to external temperature compensa-
tion over both –40 to +125°C and 0 to +80°C ranges are
presented in Motorola Applications Note AN840.
The piezoresistive pressure sensor element is a semicon-
ductor device which gives an electrical output signal propor-
tional to the pressure applied to the device. This device uses
a unique transverse voltage diffused semiconductor strain
gauge which is sensitive to stresses produced in a thin sili-
con diaphragm by the applied pressure.
Because this strain gauge is an integral part of the silicon
diaphragm, there are no temperature effects due to differ-
ences 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
Linearity refers to how well a transducer’s output follows
the equation: Vout = Voff + sensitivity x P over the operating
pressure range (see 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. Motoro-
la’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,

PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE
Motorola 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 Motorola pres-
sure sensor is designed to operate with positive differential
pressure applied, P1 > P2.
The Pressure (P1) side may be identified by using the
