Capacitive Sensor Control ICs

Capacitive sensors convert the capacitance between the electrode and an object (i.e. finger) to electrical signals. They contribute to thinner, more flexible designs compared with mechanical sensors. A broad lineup is offered in a variety of channels, interfaces, functions, and voltages, facilitating development of capacitive switching modules.
