CAV424 C/V-converter for single and differential capacitive input signals Principle Function Capacitance/Voltage-converter IC with adjustable voltage output and integrated temperature sensor Function CAV424 is an integrated capacitance-to-voltage converter.

The IC measures the capacitance of a connected capacitive measurement head against a reference capacitance and converts the difference into a DC output voltage.

CAV424 can be used as analog front end for a micro processor or as stand-alone I
