Description
The Q Touch Sensor is a high sensitivity and high noise immunity touch input device.It is based on Atmel AT42QT1070. The AT42QT1070 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.

在Q觸摸傳感器是一種高靈敏度，高抗干擾觸摸輸入device.It基於愛特梅爾AT42QT1070。該AT42QT1070調節其擴頻方式爆發，以大量抑制外部噪聲的影響，並抑制RF輻射。該QT1070採用收購的雙脈衝方法。這提供了更大的抗噪聲能力，消除了對外部採樣電容器的需要，讓觸摸感應使用單個引腳。
