Touch IC

1.GA6572 Overview

GA6572 is the capacitive touch solution designed for automotive electronics. It contains up to 42

transmitters (Tx) and 30 receivers (Rx) to provide superior touch accuracy If the sensor pitch is within 5.5 mm, the supported touch screen for automotive market is 10.1” or 10.25”; if the sensor pitch ranges from 5.5 mm to 6.5 mm , the supported touch screen size can reach up to 12.3”(aspect ratio: 8:3).

GA6572 supports up to 10 concurrent touches with real-time tracking of accurate position and motion trajectory as well as touch area. In addition,it features high noise immunity, moisture immunity and support for gloved-hand input.
