Motorola Preferred Device
0 to 50 kPa (0 to 7.25 psi)
40 mV FULL SCALE SPAN
(TYPICAL)
The MPX2050 series device is a silicon piezoresistive pressure sensors providing a
highly accurate and linear voltage output — directly proportional to the applied pressure.
The sensor is a single, monolithic silicon diaphragm with the strain gauge and a thin–film
resistor network integrated on–chip. The chip is laser trimmed for precise span and offset
calibration and temperature compensation.

VOLTAGE OUTPUT versus APPLIED DIFFERENTIAL PRESSURE
The differential voltage output of the X–ducer is directly proportional to the differential
pressure applied.
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).
Preferred devices are Motorola recommended choices for future use and best overall value.

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.
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. Common mode pressures beyond specified may result in leakage at the case–to–lead interface.
8. Exposure beyond these limits may cause permanent damage or degradation to the device.
9. Offset stability is the product’s output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

LINEARITY
Linearity refers to how well a transducer’s output follows
the equation: Vout = Voff + sensitivity x P over the operating
pressure range. There are two basic methods for calculating
nonlinearity: (1) end point straight line fit (see Figure 2) 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. Motorola’s
specified pressure sensor linearities are based on the end
point straight line method measured at the midrange pres-
sure.

Figure 3 shows the minimum, maximum and typical output
characteristics of the MPX2050 series at 25°C. The output is
directly proportional to the differential pressure and is essen-
tially a straight line.
The effects of temperature on Full–Scale Span and Offset
are very small and are shown under Operating Characteris-
tics.

Figure 4 illustrates the differential or gauge configuration
in the basic chip carrier (Case 344–15). A silicone gel iso-
lates the die surface and wire bonds from the environment,
while allowing the pressure signal to be transmitted to the sil-
icon diaphragm.
teristics 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 perfor-
mance and long term reliability. Contact the factory for in-
formation regarding media compatibility in your application.

PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE
Motorola designates the two sides of the pressure sensor
designed to operate with positive differential pressure
as the Pressure (P1) side and the Vacuum (P2) side. The
Pressure (P1) side is the side containing the silicone gel
which isolates the die. The Motorola MPX pressure sensor is
applied, P1 > P2.
The Pressure (P1) side may be identified by using the
