MPXA4250A6U (NXP)

The MPXA4250A6U is a 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 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 analogue output signal that is proportional to the applied pressure. The small form factor and high reliability of on-chip integration makes the Freescale sensor a logical and economical choice for the automotive system engineer.
