KP235
XENSIV™ - KP235 analog absolute pressure sensor for advanced automotive, industrial and consumer markets
The KP235 is a miniaturized Analog 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 analog output signal. The calibrated transfer function converts a pressure of 40 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 barometric 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.
