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 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. 7.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. 8.Warm-up Time is defined as the time required for the product to meet the specified output voltage after the Pressure has been stabilized. 9.Offset Stability is the product's output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.

Fully Integrated Pressure Sensor Schematic MP3V5050 Sensors Freescale Semiconductor 3 Pressure On-chip Temperature Compensation and Calibration Figure 3 illustrates the Differential/Gauge Sensing Chip in the basic chip carrier (Case 482A). 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 MP3V5050 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. Figure 2 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 4. The output will saturate outside of the specified pressure range. Figure 4 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. 3 Transfer Function: Vout = VS*(0.018*P+0.04) ± ERROR VS = 3.0 Vdc TEMP = 0 to 85°C Output (V) 2 TYPICAL MAX MIN 1 0 0 5 10 15 20 25 30 35 40 45 50 55 Differential Pressure (kPa) Figure 2.
