Product Description:
MPX4250AP 20KPa-250KPa Pressure Sensor For Non-automotive
Applications
Features:
The MPX4250A 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.
The MPX4250A 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, thinfilm
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.
