The 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 ratiometric 4-volt output with superior output offset characteris-
tics. Output offset errors due to change in temperature, stability to warm-up, stability to long time period, and
position sensitivity are all significantly reduced when compared to conventional compensation methods. In
addition the sensor utilizes a silicon, micromachined, stress concentration enhanced structure to provide a very
linear output to measured pressure.
These calibrated and temperature compensated sensors give an accurate and stable output over a wide tempera-
ture range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and
the like.
The output of the device is ratiometric to the supply voltage over a supply voltage range of 4.5 to 5.5 volts.

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.
