KP264XTMA1

KP264XTMA1 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 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 KP264 is designed for use in the target applications automotive applications, industrial control, consumer applications, medical applications, weather stations, and altimeters.
