- Decoupling circuit shown in Figure 3 required to meet electrical specifications.
- 1.0 kPa (kiloPascal) equals 0.145 psi.
- Offset (V off) is defined as the output voltage at the minimum rated pressure.
- Full Scale Output (V FSO) is defined as the output voltage at the maximum or full rated pressure.
- Full Scale Span (V FSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
- Accuracy (error budget) c onsists of the following:
Linearity: Output deviation from a straight line relations hip with pressure over the specified pressure range. and from the minimum or maximum operating temperature points, with zero differential pressure applied. 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 mini mum 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.
- Response Time is defined as the time fo r 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.
- Warm-up is defined as the time required for the product to m eet the specified output voltage after the Pressure has been stabilized.
- Offset stability is the product's output deviation when subjec ted to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.
- Device is ratiometric within this specified excitation range.

PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE The two sides of the pressure sensor are designated as the Pressure (P1) side and the Vacuum (P2) side. The Pressure (P1) side is the side containing fluorosilicone gel, which protects the die from harsh media. The MPX pressure sensor is designed to operate with positive differential pressure applied, P1 > P2. The Pressure (P1) side may be identified by using the table below: Nominal Transfer Value: Vout = VS (P x 0.01059 - 0.1518) ± (Pressure Error x Temp.
