3 / 13 page MPX2053 Sensors Freescale Semiconductor 3 Table 2. Operating Characteristics (VS = 10 VDC, TA = 25°C unless otherwise noted, P1 > P2) Characteristic Symbol Min Typ Max Units Pressure Range(1) 1. 1.0 kPa (kiloPascal) equals 0.145 psi. POP 0 — 50 kPa Supply Voltage(2) 2. Device is ratiometric within this specified excitation range. Operating the device above the specified excitation range may induce additional error due to device self-heating. VS — 10 16 VDC Supply Current IO — 6.0 — mAdc Full Scale Span(3) 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 related pressure. VFSS 38.5 40 41.5 mV Offset(4) 4. Offset (VOFF) is defined as the output voltage at the minimum rated pressure. VOFF –1.0 — 1.0 mV Sensitivity ∆V/∆Ρ — 0.8 — mV/kPa Linearity(5) 5. 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 VFSS, at 25°C. — -0.6 — 0.4 %VFSS Pressure Hysteresis(5) (0 to 50 kPa) — — ±0.1 — %VFSS Temperature Hysteresis(5) (–40°C to +125°C) — — ±0.5 — %VFSS Temperature Effect on Full Scale Span(5) TCVFSS –2.0 — 2.0 %VFSS Temperature Effect on Offset(5) TCVOFF –1.0 — 1.0 mV Input Impedance ZIN 1000 — 2550 Ω Output Impedance ZOUT 1400 — 3000 Ω Response Time(6) (10% to 90%) 6. Response Time is defined as the time form 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 Warm-Up Time — — 2.0 — ms Offset Stability(7) 7. Offset stability is the product’s output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test. — — ±0.5 — %VFSS |
