2 / 11 page MPXV7002 Sensors 2 Freescale Semiconductor Pressure Operating Characteristics Table 1. Operating Characteristics (VS = 5.0 Vdc, TA = 25°C unless otherwise noted. Decoupling circuit shown in Figure 3 required to meet specification.) Characteristic Symbol Min Typ Max Unit Pressure Range(1) 1. 1.0 kPa (kiloPascal) equals 0.145 psi. POP –2.0 — 2.0 kPa Supply Voltage(2) 2. Device is ratiometric within this specified excitation range. VS 4.75 5.0 5.25 Vdc Supply Current Io — — 10 mAdc Pressure Offset(3) (10 to 60 °C) @ VS = 5.0 Volts 3. Offset (Voff) is defined as the output voltage at the minimum rated pressure. Voff 2.25 2.5 2.75 Vdc Full Scale Output(4) (10 to 60 °C) @ VS = 5.0 Volts 4. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure. VFSO 4.25 4.5 4.75 Vdc Full Scale Span(5) (10 to 60 °C) @ VS = 5.0 Volts 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. VFSS 3.5 4.0 4.5 V Vdc Accuracy(6) (10 to 60 °C) 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 10 ° to 60°C, relative to 25°C. TcOffset: Output deviation with minimum rated pressure applied, over the temperature range of 10 ° to 60°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. —— ±2.5(7) 7. Auto Zero at Factory Installation: Due to the sensitivity of the MPXV7002 Series, external mechanical stresses and mounting position can affect the zero pressure output reading. Auto zero is defined as storing the zero pressure output reading and subtracting this from the device's output during normal operations. Reference AN1636 for specific information. The specified accuracy assumes a maximum temperature change of ± 5 °C between auto zero and measurement. ±6.25 %VFSS Sensitivity V/P — 1.0 —- V/kPa Response Time(8) 8. 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. tR —1.0 —- ms Output Source Current at Full Scale Output IO+ —0.1 —- mAdc Warm-Up Time(9) 9. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized. —— 20 —- ms |
