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: Typical temperature output error over the compensated temperature range of 0°C to 50°C.
Operation in Sleep Mode may affect temperature output error depending on duty cycle.
7
Total Error Band: The maximum deviation from the ideal transfer function over the entire compensated temperature and
pressure range. Includes all errors due to offset, full scale span, pressure non-linearity, pressure hysteresis, repeatability,
thermal effect on offset, thermal effect on span, and thermal hysteresis.
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 2.)
9
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.
