1. Device is ratiometric within this specified excitation range.

2. Span is defined as the algebraic difference between the output voltage at specified pressure and the output voltage at the minimum rated

pressure.

3. Offset (Voff) is defined as the output voltage at the minimum rated pressure.

4. 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.

• Offset Stability:

Output deviation, after 1000 temperature cycles, –30 to 100°C, and 1.5 million pressure cycles, with minimum

rated pressure applied.

• 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.

5. Auto Zero at Factory Installation: Due to the sensitivity of the MPXV5004G, external mechanical stresses and mounting position can affect

the zero pressure output reading. Autozeroing 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 autozero and measurement.
