Integrated Silicon Pressure Sensor

for Manifold Absolute Pressure

Applications

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

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 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.

Figure 1 shows a block diagram of the internal circuitry integrated on a pressure

sensor chip.
