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.
