T he Amplified line of low pressure sensors is based upon a proprietary technology to reduce all output offset or
common mode errors. This model provides a r atiometric 4-volt output with superior output offset c haracteristics.
Output offset errors due to change in temper ature, stability to warm-up, stability to long time period, and position
sensitivity are all significantly reduced w hen compared to conv entional compensation methods. In addition the
sensor utilizes a silicon, micromachined, stress concentr ation enhanced structure to pro vide a very linear output
to measured pressure.
These calibrated and temperature compensated sensors give an accurate and stable output over a wide
temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry
gases and the like.
T he output of the device is ratiometric to the supply voltage over a supply voltage r ange of 4.5 to 5.5 v olts.

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 0.25 TO 4.25 VOLTS
FOR MINUS TO PLUS FULL SCALE PRESSURE.
