Integrated Silicon Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated and

Calibrated

The MPXV7025G series piezoresistive transducer is a state-of-the-art

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

particularly those employing a microcontroller or microprocessor with A/D inputs.

This patented, single element 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.
