Miniaturized digital absolute pressure sensor Infineon KP466XTMA1 with automotive qualification and features
XENSIV KP466 Digital Absolute Pressure Sensor
Product Overview
The XENSIV KP466 is a high-performance, high-precision miniaturized digital absolute pressure sensor utilizing a capacitive sensing principle. It is surface micromachined with an integrated signal conditioning circuit, converting physical pressure and temperature into digital values transmitted via an SPI interface. Key features include high accuracy pressure sensing (1.0 kPa) within a 60 to 165 kPa range, a wide operating ambient temperature range (-40C to 125C), and best-in-class low power consumption with a dedicated power-down mode. The sensor offers 10-, 12-, or 14-bit resolution for pressure and temperature data, integrated signal path diagnostics, and is qualified for automotive applications according to AEC-Q103-002. Potential applications span automotive (barometric air pressure, manifold air flow, battery monitoring, seat comfort) and industrial sectors, including weather stations and altimeters.
