Touch IC

1.Overview of GA611

GA611, a capacitive touch solution integrating with self-capacitance/mutual-capacitance detection, consists of up to 23 transmitter electrodes and 11 receiver electrodes.

In addition, it supportsindependent touch keys(up to 34 self-capacitive keys or 50 mutual- capacitance keys), sliding operation and keys of different sizes, which is applicable on the covers with multi-pattern, multi-stack, and different thickness, and greatly enriches the user experience in various scenarios.
