The MPX5050/MPXV5050G 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.
