The MPX2053/MPXV2053G device is a silicon piezoresistive pressure sensor
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 sensor 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 (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
minimum rated 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 within the specified range, when this pressure is cycled to and from the
minimum or maximum rated pressure, at 25°C.
• TcSpan:
Output deviation at full rated pressure 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.
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.

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 pressure.

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 the silicone gel
which isolates the die. The Motorola MPX pressure sensor is
Part Number
designed to operate with positive differential pressure
applied, P1 > P2.
