The ATMXT144UD-SL is a touch controller containing pre-programmed firmware specifically designed for implementing a long multi-touch slider with up to 144 adjacent capacitive nodes. Its self-capacitance and mutual-capacitance acquisition, paired with its excellent intrinsic signal-to-noise performance, enables the detection and tracking of multi-finger thick gloves through a wide variety of overlay materials and thicknesses, even in the presence of moisture. With fast report rates up to 200Hz and first touch latency below 15ms, a consistent user touch experience can be achieved between the slider and an adjacent touch display. The controller incorporates internal self-tests and connected touch sensor diagnostics. ATMXT144UD-SL is offered in a small automotive qualified VQFN-56 package with wettable flanks.
