Analog Microelectronics CAV444
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 provides the complete electronics needed for the conversion of capacitive input signals into voltage output signals, which can be amplified and offset adjusted using external trimming resistors.APPLICATIONS
