MPX5700
Rev 8, 01/2007
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.
