Azoteq announces the IQS266, a miniature trackpad designed for single-layer ITO applications

IQS266 Miniature Trackpad

With the IQS266 specifically designed for single-sided ITO touch screens, the system cost can be halved compared to normal ITO solutions,” said Jean Viljoen, VP of Marketing. “Combined with the extremely low power consumption, this becomes the perfect solution for wearables and fitness trackers.

Azoteq, a pioneer in sensor fusion, today announced the release to market of the IQS266. The IQS266 is a 2×3 projected capacitive trackpad designed for low-power mobile applications.

This trackpad is specifically designed to be implemented on a single-sided ITO touch screen for wearables. A self-capacitive channel is used for wake-up, which keeps the power consumption at a low power of less than 3 uA. Other features include automatic tuning for sense electrodes, internal reference capacitor and internal regulator to reduce total system cost.
