KP467XTMA1

KP467XTMA1 is a 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. The device converts a physical pressure into a 10-, 12- or 14-bit 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. The integrated diagnostics are a special reliability feature, which allows testing the sensor cells as well as the signal path. It is used in applications such as automotive barometric air pressure sensor (BAP), automotive manifold air flow sensors (MAF), automotive battery monitoring system (BMS), automotive seat comfort system, industrial control, weather stations, and altimeters.
