Integrated Silicon Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

The MPX4250D series piezoresistive transducer is a state–of–the–art monolithic

silicon pressure sensor designed for a wide range of applications, 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. The small form factor and high reliability of on–chip integration

make the Motorola sensor a logical and economical choice for the automotive system

engineer.

Features

• Differential and Gauge Applications Available

• 1.4% Maximum Error Over 0° to 85°C

• Patented Silicon Shear Stress Strain Gauge

• Temperature Compensated Over –40° to +125°C

• Offers Reduction in Weight and Volume Compared to Existing Hybrid Modules

• Durable Epoxy Unibody Element

Applications

• Ideally Suited for Microprocessor or Microcontroller–Based Systems
