On semiconductor has launched a new touch / proximity sensing scheme to integrate the performance, cost performance and convenience of the leading industry into a single chip. Lc717a30uj high dynamic range capacitance digital converter uses mutual capacitance to detect capacitance changes as low as nanofarad level (FF). Eliminating parasitic capacitance improves the sensitivity of the detector, and its built-in noise suppression mechanism suppresses the influence of electromagnetic interference (EMI).
