Description

The new MPX7100 series pressure sensor incorporates all the innovative features of Motorola's MPX2000 series family including the patented, single piezoresistive strain gauge (Xducer) and onchip temperature compensation and calibration. In addition, the MPX7100 series has a high input impedance of typically 10 kW for those portable, low power and batteryoperated 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 420 mAmp transmission and field barometers/altimeters.
