Integrated Silicon Pressure Sensor

Applications On-Chip Signal
Conditioned, Temperature
Compensated and Calibrated
The Freescale 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 Freescale 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.
