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.
