Azoteq IQS410 IQ Switch® - ProxSense™
XY Touch Panel Controllers

Azoteq IQS410 IQ Switch® - ProxSense™ Series XY Touch Panel Controllers revolutionizes the touch panel industry by offering a cost-effective controller IC interfaced to a simplified touch panel. Azoteq IQS410 ProxSense XY Touch Panel Controllers offer class leading proximity sensitivity. The devices provide a PROXIMITY detected signal to activate features such as launching a menu screen, activating backlighting, or waking a system from sleep on the user approaching. The Azoteq IQS410 is a 6-channel capacitive sensing device that uses four channels to produce touchscreen coordinate data. Two additional channels implemented to be used as buttons with proximity and touch functionality by adding one capacitor to the design. These Azoteq touch panel controllers are ideal for use in a variety of applications, including navigation device,s media players, consumer electronics, and more.
