(Typical)
The MPX2202 devices series are 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. They are designed for use in applications such as pump/
motor controllers, robotics, level indicators, medical diagnostics, pressure
switching, barometers, altimeters, etc.

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.

Voltage Output versus Applied Differential
The differential voltage output of the sensor is directly
proportional to the differential pressure applied.
The absolute sensor has a built-in reference vacuum. The
output voltage will decrease as vacuum, relative to ambient,
is drawn on the pressure (P1) side.
The output voltage of the differential or gauge sensor
increases with increasing pressure applied to the pressure
(P1) side relative to the vacuum (P2) side. Similarly, output
voltage increases as increasing vacuum is applied to the
vacuum (P2) side relative to the pressure (P1) side.
Figure 1 illustrates a block diagram of the internal circuitry
on the stand-alone pressure sensor chip.

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 4) 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.

Relative Voltage Output
Figure 3 illustrates the differential/gauge die in the basic
chip carrier (Case 344). A silicone gel isolates the die surface
and wire bonds from the environment, while allowing the
pressure signal to be transmitted to the silicon diaphragm.
The MPX2202 series pressure sensor operating
characteristics 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
performance and long term reliability. Contact the factory for
information regarding media compatibility in your application.

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 MPX
pressure sensor is designed to operate with positive
differential pressure applied, P1 > P2.
The Pressure (P1) side may be identified by using the
following table.
