Freescale’s MPxx5004 series piezoresistive transducer is a state-of-the-art
monolithic silicon pressure sensor designed for a wide range of applications, but
particularly those employing a microcontroller or microprocessor with A/D inputs.
This sensor combines a highly sensitive implanted strain gauge with advanced
micromachining techniques, thin-film metallization, and bipolar processing to
provide an accurate, high level analog output signal that is proportional to the
applied pressure.

1. Device is ratiometric within this specified excitation range.
2. Span is defined as the algebraic difference between the output voltage at specified pressure and the output voltage at the minimum rated
pressure.
3. Offset (Voff) is defined as the output voltage at the minimum rated pressure.
4. Accuracy (error budget) consists of the following:
Linearity:
Output deviation from a straight line relationship with pressure, using endpoint 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 over the temperature range of 10 °C to 60 °C, relative to 25 °C.
Output deviation with minimum rated pressure applied, over the temperature range of 10 °C to 60 °C, relative to
25 °C.
Variation from nominal:
The variation from nominal values, for offset or full-scale span, as a percent of VFSS, at 25 °C.
5. Autozero at factory installation: Due to the sensitivity of the MPxx5004G, external mechanical stresses and mounting position can affect the
zero pressure output reading. Autozeroing is defined as storing the zero pressure output reading and subtracting this from the device's output
during normal operations. Reference AN1636 for specific information. The specified accuracy assumes a maximum temperature change of
±5 °C between autozero and measurement.

On-chip Temperature Compensation and Calibration
The performance over temperature is achieved by integrating the shear-stress strain gauge, temperature compensation,
calibration and signal conditioning circuitry onto a single monolithic chip.
Figure 3 illustrates the gauge configuration in the basic chip carrier (case 98ASB17756C). A fluorosilicone gel isolates the die
surface and wire bonds from the environment, while allowing the pressure signal to be transmitted to the silicon diaphragm.
The MPxx5004 series sensor operating characteristics are based on use of dry air as pressure media. Media, other than dry air,
may have adverse effects on sensor performance and long-term reliability. Internal reliability and qualification test for dry air, and
other media, are available from the factory. Contact the factory for information regarding media tolerance in your application.
Figure 4 shows the recommended decoupling circuit for interfacing the output of the MPxx5004 to the A/D input of the
microprocessor or microcontroller. Proper decoupling of the power supply is recommended.
Typical, minimum and maximum output curves are shown for operation over a temperature range of 10 °C to 60 °C using the
decoupling circuit shown in Figure 4. The output will saturate outside of the specified pressure range.

Pressure (P1)/Vacuum (P2) side identification
Freescale Semiconductor 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 Semiconductor pressure sensor is designed to operate with positive differential pressure applied, P1 > P2.
The pressure (P1) side may be identified by using the table below.

Minimum recommended footprint for surface mounted applications
Surface mount board layout is a critical portion of the total design. The footprint for the surface mount packages must be the
correct size to ensure proper solder connection interface between the board and the package. With the correct footprint, the
packages will self align when subjected to a solder reflow process. It is always recommended to design boards with a solder mask
layer to avoid bridging and shorting between solder pads.
