IQS9150
The IQS9150 ProxSense® IC is a generic and configurable trackpad product aimed to be suitable for numerous design variations and requirements. The IQS9150 has multitouch high-performance (linearity, accuracy, low-noise) trackpad outputs, integrated snap button options, and an on-chip gesture recognition engine. The IQS9150 features best-in-class sensitivity, signal-to-noise ratio and automatic tuning of electrodes. Low-power proximity detection allows extreme low-power operation.
