Media Resistant, Integrated Silicon

Pressure Sensor for Manifold

Absolute Pressure Applications

On-Chip Signal Conditioned,

Temperature Compensated, and

Calibrated

The Motorola MPXAZ4100A 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 small form factor and high reliability of on–chip integration makes the

Motorola MAP sensor a logical and economical choice for automotive system

designers.

The MPXAZ4100A 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.
