CAP1293 Overview
The CAP1293 is a multiple channel capacitive touch sensor controller. It contains three (3) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input is calibrated to pensate for system parasitic capacitance and automatically recalibrated to pensate for gradual environmental changes.
