1 Product Description

The KP226E0109 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 320 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.
