KP464EXTMA1

KP464EXTMA1 is a XENSIV™ high-performance, high-precision miniaturized digital absolute pressure sensor based on a capacitive sensing principle. It is surface micromachined with a monolithic integrated signal conditioning circuit. This device converts a physical pressure into a 10-, 12- or 14bit digital value and transmits the information via the SPI interface. In addition, a temperature sensor is integrated on chip. Based on the received SPI command, the 10-, 12- or 14-bit temperature information will also be transmitted via the SPI interface. This device has implemented a particular power-down mode which allows the user to even reduce the power consumption of the device. It is used in applications such as automotive barometric air pressure sensor (BAP), automotive manifold air flow sensor (MAF), automotive battery monitoring system (BMS), automotive seat comfort system, industrial control, weather stations, altimeters.
