Integrated Silicon Pressure Sensor

Manifold Absolute Pressure Sensor

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

The Motorola 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.

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 Motorola sensor a logical and economical choice for the automotive system

engineer.
