MPX7050

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MPX7050/D 50 kPa High Zin, On-Chip Temperature Compensated & Calibrated Silicon Pressure Sensors The new MPX7050 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 MPX7050 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 MPX7050 series device is a logical and economical choice for applications such as portable medical instrumentation, and remote sensing systems with 4 – 20 mAmp transmission. Features Temperature Compensated Over 0°C to +85°C Unique Silicon Shear Stress Strain Gauge Easy to Use Chip Carrier Package Options Available in Differential and Gauge Configurations Ratiometric to Supply Voltage ± 0.25% Linearity Application Examples Portable Medical Instrumentation Remote Sensing Systems Figure 1 shows a schematic of the internal circuitry on the stand–alone pressure sensor chip.
