MPX4105
Integrated Silicon Pressure Sensor
Manifold Absolute Pressure Sensor
On-Chip Signal Conditioned,
Temperature Compensated
and Calibrated
The Motorola MPX4105 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鈥揷hip integration makes the Motorola MAP
sensor a logical and economical choice for automotive system designers.
The MPX4105 series piezoresistive transducer is a state鈥搊f鈥搕he鈥揳rt, monolithic,
signal conditioned silicon pressure sensor. This sensor with its patented transducer,
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.
