• Medical application
Description
The KP212K1409 is a miniaturized Analog Manifold 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 analog output signal. The calibrated transfer function converts a pressure
of 15 kPa to 115 kPa into a voltage range of 0.5 V to 4.5 V.
The chip is packaged in a “green” SMD housing. The sensor has been primarily developed for measuring manifold
air pressure, but can also be used in other application fields. The high accuracy and the high sensitivity of the
device makes it a perfect fit for advanced automotive applications as well as in industrial and consumer
applications.
