Integrated Silicon Pressure Sensor On-Chip Signal Conditioned, Temperature Compensated and Calibrated
The MPXx5050 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
• 2.5% Maximum Error over 0° to 85°C • Ideally suited for Microprocessor or Microcontroller-Based Systems • Temperature Compensated Over -40° to +125°C • Patented Silicon Shear Stress Strain Gauge • Durable Epoxy Unibody Element • Easy-to-Use Chip Carrier Option
