Motorola’s MPXAZ4115A 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 Motorola pressure
sensor a logical and economical choice for the system designer.
The MPXAZ4115A 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.

NOTES:
1. Device is ratiometric within this specified excitation range.
2. Offset (V
off
) is defined as the output voltage at the minimum rated pressure.
3. Full Scale Output (V
FSO
) is defined as the output voltage at the maximum or full rated pressure.
4. Full Scale Span (V
FSS
) 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.

and output filtering.
For additional output filtering, please refer to
Application Note AN1646.
Figure 2 illustrates the absolute sensing chip in the basic
chip carrier (Case 482).
Figure 3 shows the recommended decoupling circuit for
interfacing the output of the integrated sensor to the A/D in-
put of a microprocessor or microcontroller. Proper decoup-
ling of the power supply is recommended.

Figure 4 shows the sensor output signal relative to pres-
sure input. Typical minimum and maximum output curves
are shown for operation over a temperature range of 0 to
85°C using the decoupling circuit shown in Figure 3. The
output will saturate outside of the specified 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 resis-
tant barrier that allows the sensor to operate reliably in
high humidity conditions as well as environments contain-
ing common automotive media. Contact the factory for
more information regarding media compatibility in your
specific application.
