The MPX4250A/MPXA4250A series 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.
SMALL OUTLINE PACKAGES
The MPX4250A/MPXA4250A series 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 Freescale
sensor a logical and economical choice for the automotive system engineer.
