Integrated Silicon Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated and

Calibrated

The MPXV7002 series piezoresistive transducers are state-of-the-art

monolithic silicon pressure sensors designed for a wide range of applications, but

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.
