Product Overview
The Infineon KP212K1409 is a miniaturized analog absolute pressure sensor IC based on a capacitive principle. It features high precision pressure sensing ( 1.0 kPa) and a ratiometric analog output, making it suitable for a wide temperature range (-40 C to 125 C). The sensor includes broken wire detection and clamping for enhanced reliability. Its calibrated transfer function converts a pressure range of 15 kPa to 115 kPa into a voltage range of 0.5 V to 4.5 V. Primarily developed for manifold air pressure measurement in two-wheeler applications, it is also ideal for industrial control, consumer, and medical applications due to its high accuracy and sensitivity.
