Infineon Technologies KP264 XENSIV™ Digital Barometric Air Pressure (dBAP) Sensor features an SPI digital interface and offers absolute air pressure measurement. The KP264 IC is surface micromachined with a monolithic integrated signal conditioning circuit implemented in BiCMOS technology. This highly accurate, highly sensitive sensor is ideal for advanced automotive, industrial, and consumer applications.
The KP264 XENSIV 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 can also 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 by an SPI command. This device has been primarily developed for measuring barometric air pressure, but can also be used in other application fields.
The KP264 is packaged in a “green” surface mounted PG-DSOF-8 housing, and features a wide -40°C to +125°C operating temperature range.
