Pressure MPX4200A Freescale Semiconductor Rev 4, 1/2009 + Integrated Silicon Pressure Sensor MPX4200A for Manifold Absolute Pressure, Series Applications, On-Chip Signal 20 to 200 kPa (2.9 to 29 psi) Conditioned, Temperature 0.3 to 4.9 V Output Compensated and Calibrated The Freescale MPX4200A series Manifold Absolute Pressure (MAP) sensor for turbo boost engine control is designed to sense absolute air Application Examples pressure within the intake manifold. This measurement can be used to Manifold Sensing for Automotive compute the amount of fuel required for each cylinder. Systems The MPX4200A series sensor integrates on-chip, bipolar op amp circuitry and thin film resistor networks to provide a high level analog output signal and Ideally suited for Microprocessor or temperature compensation. The small form factor and reliability of on-chip Microcontroller-Based Systems integration make the Freescale MAP sensor a logical and economical choice Also ideal for Non-Automotive for automotive system designers.

Device is ratiometric within this specified excitation range. 3. Offset (V ) is defined as the output voltage at the minimum rated pressure. off 4. Full Scale Output (V ) is defined as the output voltage at the maximum or full rated pressure. FSO 5. Full Scale Span (V ) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the FSS 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 V , at 25C. FSS 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. MPX4200A Sensors 2 Freescale Semiconductor
