Note: Stresse above those listed here may cause permanent damage to the device. xposure to absolute maximum rating conditions for extended periods may affect evice reliability.

The KP120 is a miniaturized absolute pressure sensor IC based on the capacitive rinciple. It is surface micromachined with a monolithic integrated signal conditioning ircuit realized in the state-of-the-art 0.8 m BiCMOS technology. As the KP120 is a high recision IC for cost critical solutions the chip is packaged in a low cost SMD housing. igh a uracy and high sensitivity enable the dedication in automotive applications as ell 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 or controlling spark advance to optimize engine efficiency.

The IC consists of a surface micromachined pressure sensor, a sigma-delta A/Dconverter,  digital filter and the SPI-interface. In normal operation, the applied pressure as to be in the range between 10 kPa and 150 kPa and the KP120, KP120 Exxxx can eliver output voltages between 0.25 V and 4.85 V.
