Figure 1 shows a block diagram of the internal circuitry on the stand-alone pressure sensor chip. Figure 1. Temperature Compensated Pressure Sensor Schematic proportional to the differential pressure applied. side relative to the pressure side. Table 1. Maximum Ratings(1)
- Exposure beyond the specified limits may cause permanent damage or degradation to the device.

- 1.0 kPa (kiloPascal) equals 0.145 psi.
- Device is ratiometric within this s pecified excitation range. Operating the device above the specified excitation range may induce additional
error due to device self-heating.
- Full Scale Span (VFSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
- Offset (Voff) is defined as the output voltage at the minimum rated pressure.
- Accuracy (error budget) c onsists of the following:
- Linearity: Output deviation from a straig ht line relationship with pressure, using end point method, over the specified pressure range.
- Pressure Hysteresis: Output deviation at any pressure within t he specified range, when this pressure is cycled to and from the minimum or maximum rated pressure, at 25°C.
- Temperature Hysteresis: Output deviation at any temperature with in the operating temperature range, after the temperature is cycled to and from the minimum or maximum operating temperature points, with zero differential pressure applied.
- TcSpan: Output deviation at full rated pressure 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.
