IQS266

The IQS266 ProxSense® IC is a 2×3 projected capacitive trackpad designed for low power mobile applications. This trackpad is perfect to implement on a single sided ITO touch screen for wearables. A self-capacitive channel is used for wake-up which keeps the power consumption in low-power less than 5 uA. Other features include automatic tuning for sense electrodes, internal reference capacitor and internal regulator to reduce total system cost.
