Freescale Semiconductor Technical Data 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. Freescale'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 Freescale BAP sensor a logical and economical choice for application designers.

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, 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 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 .
