The BASIC Serices of pressure sensors use a silicon micromachined (MEMS) pressure sensor in the most basic
configuration. The package is a ceramic surface mount configuration to provide the smallest footprint possible.
Best temperature compensation is realized when the sensor has a constant current excitation.
This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like.
Specifications are written for constant voltage of 3.0 volts.
The output of the device is ratiometric to the supply voltage..

Specification Notes
NOTE 1: ALL PARAMETERS ARE MEASURED AT 3.0 VOLT EXCITATION, FOR THE NOMINAL FULL SCALE PRESSURE AND ROOM TEMPERATURE
UNLESS OTHERWISE SPECIFIED. PRESSURE MEASUREMENTS ARE WITH NEGATIVE PRESSURE TO THE SINGLE PORT CONFIGURATION.
NOTE 2: SHIFT IS RELATIVE TO 25°C.
NOTE 3: SHIFT IS WITHIN THE FIRST YEAR OF OPERATION.
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.
