IQS550/572/525-B000 – Capacitive Trackpad/Touchscreen Controller
Projected capacitive controller with proximity, touch, snap, trackpad outputs and gestures
The IQS5xx-B000 is a projected capacitive touch and proximity trackpad/touchscreen
controller implementation on the IQS550, IQS572 and IQS525 platforms. The IQS5xx-
B000 features best in class sensitivity, signal-to-noise ratio and automatic tuning of
electrodes. Low power proximity detection allows extreme low power operation.
