| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MPX4115/D MPX4115 Integrated Silicon Pressure Sensor Altimeter/Barometer Pressure Sensor On-Chip Signal Conditioned, Temperature Compensated and Calibrated The MPX4115 series is designed to sense absolute air pressure in an altimeter or barometer (BAP) applications. Motorola's BAP sensor integrates on-chip, bipolar op amp circuitry and thin film resistor networks to provide a high level analog output signal and temperature compensation. The small form factor and high reliability of on-chip integration makes the Motorola BAP sensor a logical and economical choice for application designers. Features * 1.5% Maximum Error over 0 to 85C * Ideally suited for Microprocessor or Microcontroller-Based Systems * Patented Silicon Shear Stress Strain Gauge * Available in Absolute, Differential and Gauge Configurations * Durable Epoxy Unibody Element * Easy-to-Use Chip Carrier Option Application Examples * Altimeter * Barometer VS 3 SERIES OPERATING OVERVIEW INTEGRATED PRESSURE SENSOR 15 to 115kPa (2.18 to 16.7 psi) 0.2 to 4.8 Volts Output BASIC CHIP CARRIER ELEMENT CASE 867-08, STYLE 1 X-ducer SENSING ELEMENT THIN FILM TEMPERATURE COMPENSATION AND GAIN STAGE #1 2 GND GAIN STAGE #2 AND GROUND REFERENCE SHIFT CIRCUITRY PORT OPTION CASE 867B-04, STYLE 1 1 Vout NOTE: Pin 1 is the notched pin.

MECHANICAL CHARACTERISTICS Characteristic Weight, Basic Element (Case 867) Common Mode Line Pressure(10) Symbol -- -- Min -- -- Max -- 690 Unit Grams kPa NOTES: 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 the minimum or maximum rated pressure at 25C. * TcSpan: Output deviation over the temperature range of 0 to 85C, relative to 25C. * TcOffset: Output deviation with minimum pressure applied, over the temperature range of 0 to 85C, relative to 25C. * Variation from Nominal: The variation from nominal values, for Offset or Full Scale Span, as a percent of VFSS at 25C. 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. 2 Motorola Sensor Device Data MPX4115 SERIES FLUORO SILICONE GEL DIE COAT DIE P1 WIRE BOND STAINLESS STEEL CAP EPOXY PLASTIC CASE MPX4115A OUPUT (PIN 1) 50 pF 51 k A/D ABSOLUTE ELEMENT P2 SEALED VACUUM REFERENCE LEAD FRAME Figure 2 illustrates the absolute 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 MPX4115A 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.
