CAV444 Linear C/V-Converter for capacitive input signals Principle Function CapacitanceVoltage-converter IC with linear transfer function and adjustable output Function CAV444 is an integrated circuit for capacitive sensing applications.

The IC converts the connected input measurement capacitance into an output voltage, which is a linear function of the measurement capacitance.

CAV444 can be used as stand-alone analog signal-processing IC or as front-end for a micro processor for electronically
