　　Capacitive Touchscreen

　　Controller

　　The eKTH6308 is a single-chip touch panel controller with novel switched capacitor structure. The

　　novel SC structured AFE can sense and amplify small capacitance variations and convert them

　　into digitized data. It provides better sensitivity and noise immunity than other competitors.

　　The controller can also implement complicated algorithms for future application. With mighty

　　computing power, the controller can process lots of touch panel algorithms, including the

　　multi-finger identification and gesture reorganization. It adopts mutual capacitance approaches

　　which support true multi-touch capability.

　　The controller is designed as cost-effective processors, offering optimized performance and are

　　ideal for various touch panel applications. The eKTH6308 constructive features allow users to

　　explore into a wide variety of creative ideas on innovative products that use touch panel

　　technology.
