NOTES:
1. Measured at 6.0 Vdc excitation for 100 mmHg pressure differential. V
between full scale output and zero pressure offset.
and FSS are like terms representing the algebraic difference
FSS
2. Maximum deviation from end--point straight line fit at 0 and 200 mmHg.
3. Slope of end--point straight line fit to full scale span at 15°C and +40°C relative to +25°C.
4. Slope of end--point straight line fit to zero pressure offset at 15°C and +40°C relative to +25°C.
5. For a 0 to 300 mmHg pressure step change.
6. Stability is defined as the maximum difference in output at any pressure within P and temperature within +10°C to +85°C after:
OP
a. 1000 temperature cycles, --40°C to +125°C.
b. 1.5 million pressure cycles, 0 to 300 mmHg.
7. Recommended voltage supply: 6 V ± 0.2 V, regulated. Sensor output is ratiometric to the voltage supply. Supply voltages above +10 V may
induce additional error due to device self--heating.
8. Offset measurement with respect to the measured sensitivity when a 150k ohm resistor is connected to V and S+ output.

9. Accuracy is calculated using the following equation:
Error = {[V -- Offset)/(Sens
