The IQS572-A000 is a projected capacitive touch and proximity trackpad/touchscreen controller implementation on the IQS5XX platform. The IQS572 features best in class sensitivity, signal-to-noise ratio and automatic tuning of electrodes. Low power proximity detection allows extreme low power operation.

The IQS572-B000 is recommended for new designs.
