General Description
The Miniature Amplified Output pressure sensors is based upon a proprietary technology to reduce all output offset or common mode errors. This model provides a calibrated amplified output with superior output offset characteristics. 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 temperature 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 and operation from any D.C. supply voltage between 4.5 and 5.5 volts.

Specification Notes
(1): All parameters are measured at 5.0 volt excitiation, for the nominal full scale pressure and room temperature unless otherwise specified. Pressure measurements are with positive pressure applied to port B.
(2): Shift is relative to 25°C.
(3): Shift is within the first hour of excitation applied to the device.
(4) Measured at one-half full scale rated pressure using best straight line curve fit.
(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.
Pressure Response: for any pressure applied the response time to get to 90% of pressure applied is typically less than 500 useconds.
