Caution!
The sensors are not reverse polarity protected.
Incorrect applications of excitation voltage or ground
to the wrong pin can cause electrical failure.
Application of supply voltage above the maximum
can cause electrical failure.

Specification notes:
1. If maximum burst pressure is exceeded, even momentarily, the package may leak or burst, or the pressure sensing
die may fracture.
2. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified
pressure. Span is ratiometric to the supply voltage.
3. Total accuracy is the combined error from offset and span calibration, linearity, pressure hysteresis, and temperature
effects. Linearity is the measured deviation based on a straight line. Hysteresis is the maximum output difference at any point
within the operating pressure range for increasing and decreasing pressure. Calibration errors include the deviation of offset
and full scale from nominal values.
4. Delay time between sampling and signal change at the output.
5. The smallest change in the output voltage, given any change in pressure.
6. This is the maximum temperature shift for offset when measured between 0...85 °C relative to the 25 °C reading.
