Data Sheet: Technical Information
High Temperature Accuracy
Integrated Silicon Pressure Sensor
for Measuring Absolute Pressure,
On-Chip Signal Conditioned,
Temperature Compensated
and Calibrated
The MPXV6115V series sensor integrates on-chip, bipolar op amp circuitry
and thin film resistor networks to provide a high output signal and temperature
compensation. The small form factor and high reliability of on-chip integration
make the Freescale Semiconductor, Inc. pressure sensor a logical and
economical choice for the system designer.
The MPXV6115V series piezoresistive transducer is a state-of-the-art,
monolithic, signal conditioned, silicon pressure sensor. This sensor combines
advanced micromachining techniques, thin film metallization, and bipolar
semiconductor processing to provide an accurate, high level analog output
signal that is proportional to applied pressure.

1. Device is ratiometric within this specified excitation range.
2. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure.
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. Accuracy is the deviation in actual output from nominal output over the entire pressure range and temperature range as a percent of span
at 25°C due to all sources of error including 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 minimum or
maximum rated pressure at 25°C.
TcSpan: Output deviation over the temperature range of 0° to 85°C, relative to 25°C.
TcOffset: Output deviation with minimum pressure applied, over the temperature range of 0° to 85°C, relative to 25°C.
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. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the pressure has been stabilized.
7. Offset Stability is the product's output deviation when subjected to 1000 cycles of Pulsed Pressure, Temperature Cycling with Bias Test.

1. Exposure beyond the specified limits may cause permanent damage or degradation to the device.
2. Maximum Output Current is controlled by effective impedance from Vout to Gnd or Vout to VS in the application circuit.

Figure 2 illustrates the absolute sensing chip in the basic
Super Small Outline chip carrier (Case 482A).
Figure 3 shows a typical application circuit (output source
current operation).
Figure 4 shows the sensor output signal relative to
pressure input. Typical minimum and maximum output
curves are shown for operation over 0° to 85°C temperature
range. The output will saturate outside of the rated pressure
range.
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 MPXV6115V
series pressure sensor operating characteristics, 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.

Surface Mounting Information
MINIMUM RECOMMENDED FOOTPRINT FOR SMALL OUTLINE PACKAGE
Surface mount board layout is a critical portion of the total
design. The footprint for the semiconductor package must be
the correct size to ensure proper solder connection interface
between the board and the package. With the correct pad
geometry, the packages will self-align when subjected to a
solder reflow process. It is always recommended to fabricate
boards with a solder mask layer to avoid bridging and/or
shorting between solder pads, especially on tight tolerances
and/or tight layouts.
