Analog Microelectronics CAV424

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 provides the complete electronics needed for the conversion of single or differential capactive input signals into voltage output signals, which can be an amplified and offset adjusted using external trimming resistors.
