AT42QT1070
Seven-channel QTouch® Touch Sensor IC
The AT42QT1070 (QT1070) is a digital burst mode charge-transfer (QT™) capacitive sensor driver. The device can sense from one to seven keys, dependent on mode.
The QT1070 includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions, and the outputs are fully debounced. Only a few external parts are required for operation and no external Cs capacitors are required.
The QT1070 modulates its bursts in a spread-spectrum fashion in order to heavily suppress the effects of external noise, and to suppress RF emissions. The QT1070 uses a dual-pulse method of acquisition. This provides greater noise immunity and eliminates the need for external sampling capacitors, allowing touch sensing using a single pin.
