Overview: MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MPX4105/D MPX4105 Integrated Silicon Pressure Sensor Manifold Absolute Pressure Sensor On-Chip Signal Conditioned, Temperature pensated 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 pute 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 MPX4105 series piezoresistive transducer is a state–of–the–art, monolithic, signal conditioned silicon pressure sensor. This sensor with its patented transducer, bines 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.
