Specification Notes
note 1: All parameters are measured at 5.0 volt excitation, for the nominal full scale pressure and room temperature unless
otherwise specified. Pressure measurements are with positive pressure applied to PORT B.
note 2: Shift is relative to 25°C.
note 3: Shift is within the first hour of excitation applied to the device.
note 4: Measured at one-half full scale rated pressure using best straight line curve fit.
note 5: The voltage added to the offset voltage at full scale pressure. Nominally the output voltage range is 0.35V to 4.5V
volts for minus to plus full scale pressure.
