DATA SHEET MPX5050dp

SEMICONDUCTOR TECHNICAL DATA by MPX5050/D

The MPX5050 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 metalliza-tion, and bipolar processing to provide an accurate, high level analog output signal that is proportional to the applied pressure.

Features

 2.5% Maximum Error over 0 to 85C

 Ideally suited for Microprocessor or Microcontroller±Based Systems

 Temperature Compensated Over ± 40 to +125C

 Patented Silicon Shear Stress Strain Gauge

 Durable Epoxy Unibody Element

 Easy±to±Use Chip Carrier Option

1. 1.0kPa (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 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.

Weight, Basic Element (Case 867) 4.0 grams

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 series pressure sensor operating charac-teristics, 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 perfor-mance and long±term reliability. Contact the factory for

information regarding media compatibility in your application.

Figure 2 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 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 in-put of a microprocessor or microcontroller. Proper decoup-ling of the power supply is recommended.

PRESSURE (P1) / VACUUM (P2) SIDE IDENTIFICATION TABLE Motorola 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 Motorola MPX

pressure sensor is designed to operate with positive differen-tial pressure applied, P1 > P2.

The Pressure (P1) side may be identified by using the table below:
