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.
