Description

The KP466P 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 device has implemented a particular Power-Down Mode which allows the user to even reduce the power consumption of the

device. A special reliability feature are the integrated diagnostics, which allows testing the sensor cells as well as the signal path.

This diagnosis can be triggered with a SPI command.
