Notes:

1. Reference conditions (unless otherwise noted): Supply voltage, V =5.0 ±0.01 Vdc; T =25 °C [77 °F]. Output is ratiometric within the supply voltage range (Vs).

2. Span is the algebraic difference between the output voltage at the specified pressure and the output at zero pressure. Span is ratiometric to the supply voltage.

3. Accuracy is the combined errors 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. Response time for a 0 psi to full-scale pressure step change, 10% to 90% rise time.

5. The smallest change in the output voltage, given any change in pressure.
