1

Sensors are either 3.3 Vdc or 5.0 Vdc based on the catalog listing selected.

2

Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating voltage.

3

The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure.

4

Operating temperature range: The temperature range over which the sensor will produce an output proportional to pressure.

5

Compensated temperature range: The temperature range over which the sensor will produce an output proportional to pressure within the specified

performance limits.

6

Temperature Output Option: Continuous operation in Sleep Mode only may provide different results.

7

Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the pressure range at 25 °C [77 °F]. Includes

all errors due to pressure non-linearity, pressure hysteresis, and non-repeatability.

8

Full Scale Span (FSS): The algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits of the pressure range.

(See Figure 3 for ranges.)
