Freescale Semiconductor

The MPX4100 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.
