Technical Data

MPX4250D

Rev 5, 12/2006

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 Freescale 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

Typical Applications

• Ideally Suited for Microprocessor or Microcontroller-Based Systems
