KP234XTMA1

KP234XTMA1 is a miniaturized analogue barometric air pressure sensor IC based on a capacitive principle. It is surface micromachined with a monolithic integrated signal conditioning circuit implemented in BiCMOS technology. The sensor converts a pressure into an analogue output signal. The chip is packaged in a “green” SMD housing. The sensor has been primarily developed for measuring barometric air pressure, but can also be used in other application fields. The high accuracy and the high sensitivity of the device make it a perfect fit for advanced automotive applications as well as industrial and consumer applications. The KP234 is defined for use in target applications automotive applications (manifold air pressure measurement), industrial control, consumer applications, medical applications, weather stations, and altimeters.
