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 kΩ for 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.

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.
