Product Overview
The AT42QT1070-SSU is a digital burst mode charge-transfer capacitive Sensor Driver. The device can sense from one to seven keys, dependent on mode. It has the optimized architecture where no external components are required and only 1-pin per channel. It includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions and the outputs are fully de-bounced. It modulates its bursts in a spread-spectrum fashion in order to heavily suppress the effects of external noise and to suppress RF emissions. It 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.
