The Motorola MPX4105A 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.
Motorola’s MAP sensor integrates on–chip, bipolar op amp circuitry and thin film
resistor networks to provide a high output signal and temperature compensation. The
small form factor and high reliability of on–chip integration make the Motorola MAP
sensor a logical and economical choice for the automotive system designer.

The MPX4105A series piezoresistive transducer is a state–
of–the–art, monolithic, signal conditioned, silicon pressure
sensor. This sensor, with its patented X–ducer, combines
advanced micromachining techniques, thin film metallization
and bipolar semiconductor processing to provide an accurate,
high level analog output signal that is proportional to applied
pressure. A vacuum is sealed behind the sensor diaphragm
providing a reliable pressure reference.
Figure 1 shows a block diagram of the internal circuitry
integrated on the stand–alone pressure sensing chip.
