SEMICONDUCTOR TECHNICAL DATA  
Motorola Preferred Device  
0 to 100 kPa (0 to 14.5 psi)  
40 mV FULL SCALE SPAN  
(TYPICAL)  
The new MPX7100 series pressure sensor incorporates all the innovative features of  
Motorola’s MPX2000 series family including the patented, single piezoresistive strain  
gauge (X–ducer) and on–chip temperature compensation and calibration. In addition, the  
MPX7100 series has a high input impedance of typically 10 kfor those portable, low  
power and battery–operated applications. This device is suitable for those systems in  
which users must have a dependable, accurate pressure sensor that will not consume  
significant power. The MPX7100 series device is a logical and economical choice for  
applications such as portable medical instrumentation, remote sensing systems with  
4–20 mAmp transmission and field barometers/altimeters.

Figure 1. Temperature Compensated Pressure Sensor Schematic  
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.
