Accuracy
(5)
(0 to 85 °C)
5.Accuracy is the deviation in actual output from nominal output over the entire pressure range and temperature range as a percent of span at
25 °C due to all sources of error including 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 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 V

3 On-chip Temperature Compensation and Calibration
Figure 3 illustrates the absolute sensing chip in the basic super small outline chip carrier (case 98ARH99066A).
Figure 4 shows a typical application circuit (output source current operation).
Figure 5 shows the sensor output signal relative to pressure input. Typical minimum and maximum output curves are shown for
operation over 0 to 85 °C temperature range. The output will saturate outside of the rated pressure range.
A fluorosilicone gel isolates the die surface and wire bonds from the environment, while allowing the pressure signal to be
transmitted to the silicon diaphragm. The MPXH6400A/MPXHZ6400A pressure sensor operating characteristics, 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.
