Integrated Silicon Pressure Sensor

for Manifold Absolute Pressure

Applications

On-ChipSignal Conditioned,

Temperature Compensated

and Calibrated

The Motorola MPX4100A/MPXA4100A 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 MPX4100A/MPXA4100A 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.
