PXM0091

Azoteq Pxm0091

The IQS9150 is a generic and configurable trackpad device aimed at being suitable for numerous design variations and requirements. The PXM0091 utilizes the IQS9150 to provide high-performance multi-touch (linearity, accuracy, low-noise) trackpad outputs, switch input, and an on-chip gesture recognition engine. The PXM0091 features best-in-class sensitivity, signal-to-noise ratio, and automatic tuning of electrodes. The PXM0091 also has user-configurable virtual buttons, sliders, and wheels that can be superimposed onto the trackpad area, with easy-to-integrate virtual sensor outputs. Low-power proximity detection allows extremely low-power operation.
