The ADCA series of Amplified low pressure sensors are 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 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 en-
hanced 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 over a supply voltage range of 4.5 to 5.5 volts.

Specification Notes
Note 1: Part number is available in Standard Compensation Temperature Range only.
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.
Note 6: Parameter is characterized and not 100% tested.
All parameters are measured at 5.0 volt excitation and room temperature unless otherwise specified. Pressure
measurements are with positive pressure applied to PORT B
Pressure Response: for any pressure applied the response time to get to 90% of pressure applied is typically less
than 500 useconds.
Note 2: Shift is relative to 25°C between standard, industrial, or military compensated temperature
range endpoints.
