Product Descriptions

The MPX4250A/MPXA4250A Manifold Absolute Pressure (MAP) sensor for engine control is designed to sense absolute air pressure within the 

intake manifold. This measurement can be used to compute the amount of fuel required for each cylinder.

The MPX4250A/MPXA4250A piezoresistive transducer is a state-of-the-art monolithic silicon pressure sensor designed for a wide range of 

applications, particularly those employing a microcontroller or microprocessor with A/D inputs. This 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. The small form factor and high reliability of on-chip integration make the NXP sensor a logical and 

economical choice for the automotive system engineer.
