Product Description
The KP264 is a miniaturized Digital 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 a 10-bit digital value and sends the
information via the SPI interface. In addition, a temperature sensor is
integrated on chip. Based on the received SPI command, the 10-bit
temperature information will be transmitted via the SPI interface.
A special reliability feature is the integrated diagnostic mode, which
allows testing the sensor cells as well as the signal path. This diagnosis
can be simply triggered with a SPI command.
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, high sensitivity and
reliability features of the device makes it a perfect fit for advanced automotive applications as well as in industrial
and consumer applications.
