The MPX4250D series piezoresistive transducer is a stateoftheart 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, thinfilm metallization, and bipolar processing to provide an accurate, high level analog output signal that is proportional to the applied pressure.
