As Is With Change As Is With Change As Is With Change As Is With Change
The Ampli ed line of low pressure sensors is based upon a proprietary technology to reduce all output o set or com-
mon mode errors. This model provides a ratiometric 4-volt output with superior output o set characteristics. Output
o set errors due to change in temperature, stability to warm-up, stability to long time period, and position sensitivity
are all signi cantly 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 temperature
range. This series is intended for use with non-corrosive, non-ionic working uids 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.

Speci cation 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 SPAN IS THE ALGEBRAIC DIFFERENCE BETWEEN FULL SCALE OUTPUT VOLTAGE AND THE OFFSET VOLTAGE.
All Sensors reserves the right to make changes to any products herein. All Sensors does not assume any liability arising out of the application or use of any product or circuit described
herein, neither does it convey any license under its patent rights nor the rights of others.
Pressure Response: for any pressure applied the response time to get to 90% of pressure applied is typically less than 500 useconds.
