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 kW 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.
