KP236 - Miniaturized Absolute Pressure Sensor IC with Programmable Transfer Function

KP236 block diagram

The KP236 is a miniaturized absolute pressure sensor IC based on the capacitive principle. It is surface-micromachined with a monolithic integrated signal conditioning circuit, implemented in state-of-the-art 0.5 micron robust BiCMOS technology. Because the KP236 is a high-precision IC for cost critical solutions, the chip is packaged in a "green" low-cost SMD (surface-mounted device) PG-DSFO-8-16 housing. The sensor was developed for measurement of barometric air pressure (BAP). This is an important parameter in engine management applications to compute the air-fuel ratio provided to the engine and for controlling spark advance to optimize engine efficiency. High accuracy and robustness make it an ideal fit for automotive and industrial applications.
