Media Resistant and
High Temperature Accuracy
Integrated Silicon Pressure Sensor
for Measuring Absolute Pressure,
On-Chip Signal Conditioned,
Temperature Compensated
and Calibrated
The MPXAZ6115A series sensor integrates on-chip, bipolar op amp circuitry
and thin film resistor networks to provide a high output signal and temperature
compensation. The sensor's packaging has been designed to provide resistance
to high humidity conditions as well as common automotive media. 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 MPXAZ6115A 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.
Figure 1 shows a block diagram of the internal circuitry integrated on a
pressure sensor chip.

Sensitivity
1. Device is ratiometric within this specified excitation range.
2. Offset (Voff) is defined as the output voltage at the minimum rated pressure.
3. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure.
4. 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.
5. 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.
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. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the pressure has been stabilized.
8. Offset Stability is the product's output deviation when subjected to 1000 cycles of Pulsed Pressure, Temperature Cycling with Bias Test.

Figure 4. Output versus Absolute Pressure
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 gel die coat isolates the die surface and wire bonds from
the environment, while allowing the pressure signal to be
transmitted to the sensor diaphragm. The gel die coat and
durable polymer package provide a media resistant barrier
that allows the sensor to operate reliably in high humidity
conditions as well as environments containing common
automotive media. Contact the factory for more information
regarding media compatibility in your specific application.

MINIMUM RECOMMENDED FOOTPRINT FOR SMALL AND SUPER SMALL PACKAGES
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.
