CAV444 Converter IC for capacitive signals

CAV444 is a capacitance-to-voltage converter IC for the measurement of single capacitances. Its ratiometric output voltage signal is proportional to the input capacitance. CAV444 can be used as stand-alone IC or as front end for µC. Its wide capacitance measurement range and high sensitivity allow various applications.
