1.GA6571 touch IC Overview
GA6571 touch IC is the capacitive touch solution designed for automotive electronics. It is a single-chip solution that can support up to 10 touch points, with high sensitivity and accuracy.
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 touch IC 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, which can help to improve the user experience when using touch-based interfaces. It is also designed to be power-efficient, which can help to extend battery life in mobile devices.
Goodix is a leading provider of touch controllers and other semiconductor solutions, and the GA6571 is one of the many products in their portfolio.
