The IQS9150 ProxFusion® IC is a generic and configurable trackpad product aimed to be suitable for
numerous design variations and requirements. The IQS9150 has multi-touch 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 extremely low-power operation.
