Applications
The Amplified line of middle pressure sensors is based upon a proprietary package technology to reduce errors. This model provides a
ratiometric 4.5-volt output span 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, 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 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.
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
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. ABSOLUTE DEVICES ARE WITH PRESSURE APPLIED TO PORT A.
2) SHIFT IS RELATIVE TO 25°C.
4) MEASURED AT ONE-HALF FULL SCALE RATED PRESSURE USING BEST STRAIGHT LINE CURVE FIT FOR THE SPAN INDICATED.
5) THE VOLTAGE ADDED TO THE OFFSET VOLTAGE AT FULL SCALE PRESSURE. NOMINALLY THE OUTPUT VOLTAGE RANGE IS 0.25 TO 4.75 VOLTS FOR MINUS TO
PLUS FULL SCALE PRESSURE.
6) PARAMETER IS COMPUTED AS MAXIMUM FOR DESIGN REFERENCE AND IS NOT TESTED.
7) MAXIMUM DIFERENCE IN OUTPUT AT ANY PRESSURE WITHIN THE OPERATING PRESSURE RANGE AND COMPENSATED TEMPERATURE RANGE AFTER: A) 1000
TEMPERATURE CYCLES AND B) 1.0 MILLION PRESSURE CYCLES.
8) RESPONSE TIME FOR A ZERO TO FULL SCALE PRESSURE STEP CHANGE, 10% TO 90% RISE TIME.
