The MPX5100 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 metalliza- tion, and bipolar processing to provide an accurate, high level analog output signal that is proportional to the applied pressure.
The MPX5100 pressure sensor family provides a monolithic silicon transducer with built‑in amplification, temperature compensation and calibration. It delivers a linear analog voltage proportional to applied pressure and is suited for microcontroller‑based systems.
