Azoteq IQS9150/IQS9151 ProxSense® Sensors
Azoteq IQS9150/IQS9151 ProxSense® Sensors are generic and configurable trackpad devices suitable for numerous design variations and requirements. These sensors come with multitouch high-performance (linearity, accuracy, and low-noise) trackpad outputs, integrated snap button options, and an on-chip gesture recognition engine. The IQS9150 sensors feature best-in-class sensitivity, signal-to-noise ratio, and automatic tuning of electrodes. These proximity sensors come with user-configurable virtual buttons, sliders, and wheels that can be superimposed onto the trackpad area. It also has easy-to-integrate virtual sensor outputs. The IQS9150 sensors are ideal for gaming controllers, headphones, mobile devices, tablet and notebook accessories, Point-of-Sale (POS), and industrial (control panels, medical devices, and aircraft cockpits).
