Microchip AT42QT2120 QTouch 12-Channel Touch Sensor IC is a new capacitive touch controller for buttons, sliders, and wheels that delivers the longest capacitive proximity sensing range in the market today, stretching more than 10 inches (25cm). This longer range for the AT42QT2120 QTouch 12-Channel Touch Sensor IC, combined with other standard touch advantages—in noise immunity, Adjacent Key Suppression® (AKS®), conducted immunity, reduced BOM, and moisture tolerance—make Microchip the premier supplier for capacitive touch user interfaces. The new capacitive touch sensing algorithm in the Microchip AT42QT2120 QTouch 12-Channel Touch Sensor IC enables superior sensing because of faster acquisition times and shorter burst lengths that provide superior sensing range.
