DESCRIPTION
High accuracy and high sensitivity enable the dedication in automotive applications as well as consumer products. In the automotive field the manifold air pressure (MAP) and barometric air pressure (BAP) are important parameters to compute the air-fuel ratio provided to the engine and for controlling spark advance to optimize engine efficiency. The IC consists of a surface micromachined pressure sensor, a sigma-delta A/Dconverter, a digital filter and the SPI-interface. In normal operation, the applied pressure has to be in the range between 10 kPa and 150 kPa and the KP120, KP120 Exxxx can deliver output voltages between 0.25 V and 4.85 V.
