The MPXV4006G 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.

NOTES:
1. Device is ratiometric within this specified excitation range.
2. 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.
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 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.
• Offset Stability:
Output deviation, after 1000 temperature cycles, 30 to 100°C, and 1.5 million pressure cycles, with
minimum rated pressure applied.
• TcSpan:
Output deviation over the temperature range of 10 to 60°C, relative to 25°C.
• TcOffset:
Output deviation with minimum rated pressure applied, over the temperature range of 10 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. Auto Zero at Factory Installation: Due to the sensitivity of the MPXV4006G, external mechanical stresses and mounting position can affect
the zero pressure output reading. To obtain the 5% FSS accuracy, the device output must be “autozeroed’’ after installation. Autozeroing
is defined as storing the zero pressure output reading and subtracting this from the device’s output during normal operations.

Figure 3 shows the recommended decoupling circuit for interfacing the output of the integrated sensor to the A/D input
of a microprocessor or microcontroller. Proper decoupling of
the power supply is recommended.
Figure 4 shows the sensor output signal relative to pressure input. 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 3. The
output will saturate outside of the specified pressure range.

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 2 illustrates the gauge configuration in the basic chip
carrier (Case 482). 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 MPXV4006G 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

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.
