MOTOROLA Order this document by MPX7100/D MPX7100/D SEMICONDUCTOR TECHNICAL DATA 100 kPa High Zin, On-Chip Temperature Compensated & Calibrated Silicon Pressure Sensors The new MPX7100 MPX7100 series pressure sensor incorporates all the innovative features of Motorola's MPX2000 MPX2000 series family including the patented, single piezoresistive strain gauge (X­ducer) and on­chip temperature compensation and calibration. In addition, the MPX7100 MPX7100 series has a high input impedance of typically 10 k for those portable, low power and battery­operated applications. This device is suitable for those systems in which users must have a dependable, accurate pressure sensor that will not consume significant power. The MPX7100 MPX7100 series device is a logical and economical choice for applications such as portable medical instrumentation, remote sensing systems with 4 ­ 20 mAmp transmission and field barometers/altimeters.

Temperature Compensated Pressure Sensor Schematic VOLTAGE OUTPUT versus APPLIED DIFFERENTIAL PRESSURE The differential voltage output of the X­ducer is directly proportional to the differential pressure applied. The absolute sensor has a built­in reference vacuum. The output voltage will decrease as vacuum, relative to ambient, is drawn on the pressure (P1) side. The output voltage of the differential or gauge sensor increases with increasing pressure applied to the pressure (P1) side relative to the vacuum (P2) side. Similarly, output voltage increases as increasing vacuum is applied to the vacuum (P2) side relative to the pressure (P1) side. Preferred devices are Motorola recommended choices for future use and best overall value. Senseon and X­ducer are trademarks of Motorola, Inc.

Device is ratiometric within this specified excitation range. Operating the device above the specified excitation range may induce additional error due to device self­heating. 3. 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. 4. Offset (Voff) is defined as the output voltage at the minimum rated pressure. 5. Accuracy (error budget) consists of the following: · Linearity: Output deviation from a straight line relationship with pressure, using end point method, 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 at full rated pressure 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. 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. Common mode pressures beyond specified may result in leakage at the case­to­lead interface. 8. Exposure beyond these limits may cause permanent damage or degradation to the device. 9. Offset stability is the product's output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test. 2 Motorola Sensor Device Data MPX7100 MPX7100 SERIES LINEARITY Linearity refers to how well a transducer's output follows the equation: Vout = Voff + sensitivity x P over the operating pressure range. There are two basic methods for calculating nonlinearity: (1) end point straight line fit (see Figure 2) or (2) a least squares best line fit. While a least squares fit gives the "best case" linearity error (lower numerical value), the calculations required are burdensome. Conversely, an end point fit will give the "worst case" error (often more desirable in error budget calculations) and the calculations are more straightforward for the user. Motorola's specified pressure sensor linearities are based on the end point straight line method measured at the midrange pressure.
