The NXP MPX5700DP stands as a significant component in the realm of integrated pressure sensors, designed to deliver reliable and precise measurements for a wide array of applications. This device encapsulates advanced micromachining technology and on-chip signal conditioning, making it a versatile solution for engineers and designers.
Key Features and Construction
At its core, the MPX5700DP is a monolithic silicon pressure sensor. It incorporates a thin-film metallized cell and a piezoresistive transducer fabricated on a single silicon chip. This integration allows for the direct measurement of applied pressure, which is converted into a high-level analog output signal. The sensor is engineered to measure absolute pressure from 0 to 700 kPa (0 to 101.5 psi), with a typical supply voltage of 5.0 V DC. Its robust construction includes a protective gel coating, making it suitable for use in harsh environments where it might be exposed to contaminants or humidity.
Superior Performance and On-Chip Signal Conditioning
A defining characteristic of the MPX5700DP is its exceptional temperature compensation and calibration. The on-chip signal conditioning circuitry provides a high-level analog output that is proportional to the applied pressure. This built-in calibration ensures accuracy and stability across a wide operating temperature range of -40°C to +125°C, eliminating the need for additional external components and simplifying the design-in process. The output is ratiometric to the supply voltage, further enhancing its ease of use in microcontroller-based systems.
Diverse Application Spectrum
The versatility of this sensor makes it ideal for numerous fields. It is predominantly used in:
Automotive Systems: Monitoring of manifold absolute pressure (MAP), barometric pressure, and other engine functions.
