Integrated Silicon Pressure Sensor
On-Chip Signal Conditioned,
Temperature Compensated and
Calibrated
The MPXV7002 series piezoresistive transducers are state-of-the-art
monolithic silicon pressure sensors designed for a wide range of applications, but
particularly those employing a microcontroller or microprocessor with A/D inputs.
This 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
• 2.5% Typical Error over +10°C to +60°C with Auto Zero
• 6.25% Maximum Error over +10°C to +60°C without Auto Zero
• Ideally Suited for Microprocessor or Microcontroller-Based Systems
• Thermoplastic (PPS) Surface Mount Package
• Temperature Compensated over +10° to +60°C
• Patented Silicon Shear Stress Strain Gauge
• Available in Differential and Gauge Configurations
Typical Applications
• Hospital Beds
•HVAC
• Respiratory Systems
• Process Control
