General Description
The Miniature series pressure sensors are based upon a proprietary technology to reduce the size of the sensor and

yet maintain a high level of performance. This model provides a calibrated millivolt 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
The output of the device is ratiometric to the supply voltage and operation from any D.C. supply voltage.

Specification Notes
1: All parameters are measured at 12.0 volt excitation, for the nominal full scale pressure and room temperature unless
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.
note
otherwise specified.
Pressure Response: for any pressure applied the response time to get to 90% of pressure applied is typically less
than 100 useconds.
