These Barometric pressure sensors are based upon a proprietary package technology to reduce errors. This
model provides a fixed 4-volt output with superior output characteristics. The sensor housing has been designed
specifically to reduce package induced parasitic stress and strain. In addition the sensor utilizes a silicon,
micromachined (MEMS) structure to provide a very linear output to measured pressure. The sensor embodies a
vacuum reference.
These calibrated and temperature compensated sensors give an accurate and stable output over a wide
temperature range. Each sensor is internally compensated using an ASIC compensation technique. This series is
intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like.

Specification Notes
NOTE 1: ALL PARAMETERS ARE MEASURED AT 5.0 VOLT EXCITATION FOR RATIOMETRIC PARTS AND 12.0 FOR PARTS WITH INTERNAL REFERENCE, FOR
THE NOMINAL FULL SCALE PRESSURE AND ROOM TEMPERATURE UNLESS OTHERWISE SPECIFIED.
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.
