(Typical)
The MPX2010 series silicon piezoresistive pressure sensors provide a very
accurate and linear voltage output directly proportional to the applied pressure.
These sensors house a single monolithic silicon die with the strain gauge and
thin film resistor network integrated. The sensor is laser trimmed for precise
span, offset calibration and temperature compensation.

1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2. Device is ratiometric within this specified excitation range. Operating the device at a different 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. 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.
6. 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 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).

On-Chip Temperature Compensation and Calibration
Figure 2. shows the output characteristics of the MPX2010
series at 25°C. The output is directly proportional to the
differential pressure and is essentially a straight line.
The effects of temperature on full scale span and offset are
very small and are shown under Operating Characteristics.
This performance over temperature is achieved by having
both the shear stress strain gauge and the thin-film resistor
circuitry on the same silicon diaphragm. Each chip is
dynamically laser trimmed for precise span and offset
calibration and temperature compensation.
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 MPX2010 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

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.

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 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.
