IQS525-A000

The IQS525-A000 is a projected capacitive touch and proximity trackpad/touchscreen controller implementation on the IQS550 platform. The IQS525 features best in class sensitivity, signal-to-noise ratio and automatic tuning of electrodes. Low power proximity detection allows extreme low power operation.

The IQS525-B000  is recommended for new designs.
