GA6571 10-Point Capacitive Touch Controller for Automotives

Description

1.Overview

GA6571 is the capacitive touch solution designed for automotive electronics. It contains up to 32

transmitters (Tx) and 24 receivers (Rx) to provide superior touch accuracy and is applicable to “8”

touch screens for the automotive market. If the sensor pitch is within 5.5mm, the supported touch screen

size can reach up to 10.25”.

GA6571 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

supports for gloved-hand input.
