Motorola Preferred Device  
0 to 100 kPa (0 to 14.5 psi)  
40 mV FULL SCALE SPAN  
(TYPICAL)  
The MPX2100 and MPX2101 series device is a silicon piezoresistive pressure sensors  
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 chip 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.  
The absolute sensor has a built–in reference vacuum. The output voltage will decrease  
as vacuum, relative to ambient, is drawn on the pressure (P1) side.  
The output voltage of the differential or gauge sensor increases with increasing  
pressure applied to the pressure (P1) side relative to the vacuum (P2) side. Similarly,  
output voltage increases as increasing vacuum is applied to the vacuum (P2) side  
relative to the pressure (P1) side.  
Preferred devices are Motorola recommended choices for future use and best overall value.
