PRESSURE SENSOR

The MPX5010 series piezoresistive transducer is a state±of±the±art monolithic silicon

0 to 10 kPa (0 to 1.45 psi)

0.2 to 4.7 V OUTPUT

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 metalliza-

 

tion, and bipolar processing to provide an accurate, high level analog output signal that

 

is proportional to the applied pressure.

NOTES:

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 rated 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 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.

10.Common mode pressures beyond what is specified may result in leakage at the case±to±lead interface.

ON±CHIP TEMPERATURE COMPENSATION, CALIBRATION AND SIGNAL CONDITIONING

Figure 2 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 MPX5010 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 3 shows a typical decoupling circuit for interfacing the integrated sensor to the A/D input of a microprocessor. 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 0° to 85°C using the decoupling circuit below. (The output will saturate outside of the specified pressure range.)
