The MPXx5050 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 patented, single element transducer combines 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.

Sensitivity
1. 1.0 kPa (kiloPascal) equals 0.145 psi.
2.Device is ratiometric within this specified excitation range.
3.Offset (Voff) is defined as the output voltage at the minimum rated pressure.
4.Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure.
5.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.
6.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.
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.
Variation from Nominal: The variation from nominal values, for Offset or Full Scale Span, as a percent of VFSS at 25°C.
7.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.
8.Warm-up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized.
9.Offset Stability is the product's output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

On-chip Temperature Compensation and Calibration
Figure 3 illustrates the Differential/Gauge Sensing Chip in
the basic chip carrier (Case 867). A fluorosilicone gel isolates
the die surface and wire bonds from the environment, while
allowing the pressure signal to be transmitted to the sensor
diaphragm.
The MPX5050/MPXV5050G series pressure sensor
operating characteristics, and 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.
Figure 2 shows the sensor output signal relative to
pressure 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 4.
The output will saturate outside of the specified pressure
range.
Figure 4 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.

PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE
Freescale 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 fluorosilicone gel
which protects the die from harsh media. The MPX pressure
