Product Description
Product Overview
The KP234 is a high-precision, miniaturized Analog Barometric Air Pressure Sensor IC utilizing a capacitive principle and BiCMOS technology. It offers a ratiometric analog output proportional to pressure, with a calibrated transfer function converting 40 kPa to 115 kPa into 1.33 V to 4.70 V. Designed for automotive, industrial, and consumer applications, it features high accuracy (1.5 kPa), a wide temperature range (-40 C to 125 C), broken wire detection, and is housed in a green 8-pin SMD package. It is automotive qualified.
