Integrated Silicon Pressure Sensor
for Manifold Absolute Pressure
Applications
On-Chip Signal 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.
