SEMICONDUCTOR TECHNICAL DATA  
The MPX2700A series device is a silicon piezoresistive pressure sensor providing a  
highly accurate and linear voltage output — directly proportional to the applied pressure.  
The sensor is a single monolithic silicon diaphragm with the strain gauge and a thin–film  
resistor network integrated on–chip. The sensor is laser trimmed for precise span and  
offset calibration and temperature compensation.

VOLTAGE OUTPUT versus APPLIED DIFFERENTIAL PRESSURE  
The differential voltage output of the X–ducer is directly proportional to the  
differential pressure applied.  
3
The output voltage of the differential or gauge sensor increases with  
increasing pressure applied to the pressure side (P1) relative to the vacuum  
side (P2). Similarly, output voltage increases as increasing vacuum is applied to  
the vacuum side (P2) relative to the pressure side (P1).
