The Atmel AT42QT1111-AU is a certified capacitive touch sensing device that uses the Charge Transfer technology patented by Atmel. With its 8 digital sensing channels, it can detect light pressure ranges, allowing for precise and accurate detection and tracking of human finger contact. It is also capable of detecting multiple touchpoints, up to 8 simultaneous touchpoints, making it an ideal solution for tactile user interfaces. Furthermore, it is easy to implement and only requires minimal software programming for integration.

The AT42QT1111-AU operates using an innovative tuning method that is known as the Frequency Modulation (FM) method. By performing complex calculations on the time-varying electric charge between a finger and the sensing electrode, it can accurately sense the presence and location of the finger. This method enables very accurate tracking of the finger position as it moves across the touch sensor surface. Additionally, it is self calibrating so it can accurately detect contact even if there is any change in the ambient conditions, such as humidity or temperature.

The ease of implementation of the AT42QT1111-AU makes it an attractive and cost-effective solution for a wide range of applications. Its low power consumption makes it ideal for mobile devices and wearables. It can also be used for industrial and automotive applications that require robust and resilient touch sensing solutions. The AT42QT1111-AU is also certified for safety standards, making it suitable for medical, healthcare and other related applications that require reliable services.
