Integrated Silicon Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated and

Calibrated

The MPX5700 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.
