The Infineon digital absolute pressure sensor is a miniaturized digital barometric air pressure sensor IC based on a capacitive principle. It is surface micro machined 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.
