Time(7) 1 kPa (kiloPascal) equals 0.145 PSI. Device is ratiometric within this specified excitation range. Offset (VOFF) is defined as the output voltage at the minimum rated pressure. Full Scale Output (VFSO) is defined as the output voltage at the maximum or full rated pressure. 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. 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 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 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 for the incremental changed in the output to go from 10% to 90% of its final value when subjected to a specified step change in pressure. Warm-Up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized. Offset Stability is the product’s output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

A fluorosilicone gel isolates the die surface and wire bonds from the environment, while allowing the pressure signal to be transmitted to the sensor diaphragm. The MPVZ5150 series pressure sensor operating characteristics, and internal reliability and qualification tests are based on use of dry air as the pressure media. Media, other than dry air, may have adverse effects on sensor performance and long-term reliability. Contact the factory for information regarding media compatibility in your application. Stainless Steel Cap Die Gel Die Coat Figure 4 shows the sensor output signal relative to pressure input. Typical, minimum, and maximum output curves are shown for operation over a temperature range of 0° to 85°C using the decoupling circuit shown in Figure 3. The output will saturate outside of the specified pressure range. Figure 3 shows the recommended decoupling circuit for interfacing the output of the integrated sensor to the A/D input of a microprocessor or microcontroller. Proper decoupling of the power supply is recommended. +5 V P1 Thermoplastic Case Wire Bond Vout OUTPUT Vs Lead Frame IPS 1.0 μF P2 GND 0.01 μF 470 pF Die Bond Differential Sensing Element Figure 2.

The Pressure (P1) side is the side containing fluorosilicone gel which protects the die from harsh media. The MPX pressure Part Number sensor is designed to operate with positive differential pressure applied, P1 > P2. The Pressure (P1) side may be identified by using the table below: Case Type Pressure (P1) Side Identifier MPVZ5150GC6T1 482A Side with Port Attached MPVZ5150GC7U 482C Side with Port Attached MINIMUM RECOMMENDED FOOTPRINT FOR SURFACE MOUNTED APPLICATIONS Surface mount board layout is a critical portion of the total design. The footprint for the surface mount packages must be the correct size to ensure proper solder connection interface between the board and the package. With the correct footprint, the packages will self align when subjected to a solder reflow process. It is always recommended to design boards with a solder mask layer to avoid bridging and shorting between solder. Figure 5.
