NOTES:

1. Measured at 6.0 Vdc excitation for 100 mmHg pressure differential. VFSS and FSS are like terms representing the algebraic difference be-

tween full scale output and zero pressure offset.

2. Maximum deviation from end–point straight line fit at 0 and 300 mmHg.

3. Slope of end–point straight line fit to full scale span at 0

°C and +85°C relative to +25°C.

4. Slope of end–point straight line fit to zero pressure offset at 0

°C and +85°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 POP and temperature within +10°C to + 85°C after:

a. 1000 temperature cycles, –40

°C to +125°C.

b. 1.5 million pressure cycles, 0 to 300 mmHg.

7. Operating characteristics based on positive pressure differential relative to the vacuum side (gauge/differential).

8. 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.

9. Offset measurement with respect to the measured sensitivity when a 150k ohm resistor is connected to VS and S+ output.
