MPXV7025 Rev 6, 10/2012
Integrated Silicon Pressure Sensor On-Chip Signal Conditioned, Temperature Compensated and Calibrated
The MPXV7025 series piezoresistive transducer is a state-of-the-art monolithic silicon pressure sensor designed for a wide range of applications, but particularly those employing a microcontroller or microprocessor with A/D inputs. This patented, single element transducer combines advanced micromachining techniques, thin-film metallization, and bipolar processing to provide an accurate, high level analog output signal that is proportional to the applied pressure.
Features
• 5.0% Maximum Error Over 0 to 85C • Ideally Suited for Microprocessor or Microcontroller-Based Systems • Temperature Compensated Over –40 to +125C • Thermoplastic (PPS) Surface Mount Package • Patented Silicon Shear Stress Strain Gauge • Available in Differential and Gauge Configurations
MPXV7025 Series
-25 to 25 kPa (-3.6 to 3.6 psi) 0.2 to 4.7 V Output
Application Examples
• Respiratory Systems • Process Control • Patient Monitoring • Remote Monitoring Devices
