Capacitive sensing is a powerful and increasingly popular tool for interface design. It offers a fast and reliable way to detect the presence and movements of objects, with or without contact. The AT42QT1011-TSHR is a single-touch QMatrix family sensor from Atmel, a popular provider of various system processors.
This AT42QT1011-TSHR capacitive touch device is designed for use in solid state capacitive typing keyboards. Its built-in detection and touch management block executes a robust and sensitive approach for efficient detection of finger press actions. The device contains a dual-channel DSP processing unit, digital communication interface and integrated analog front-end.
The AT42QT1011-TSHR provides a great digital interface for various types of applications that require a sensor. It can be used to implement switches, knobs and sliders, as well as gesture-based interfaces. It is particularly suitable for typing keyboards, as they do not require very fast detection times.
AT42QT1011-TSHR features a range of outstanding features, including variable detection threshold settings, noise immunity, wide dynamic range, and superior or advanced noise canceling capabilities. The sensor also provides outputs in analog and PWM format. Furthermore, its wide applicability, low power consumption and small package size makes it suitable to be used in notebook PCs and tablets.
The AT42QT1011-TSHR capacitive touch sensor works on the principle of detecting changes in the capacitance of an electrode. This device provides an array of settings that allow the designer to change the detection sensitivity and power saving mode. When the sensor is triggered, it sends a signal to the embedded controller, which then interprets the signal and performs the required task.
A signal-to-noise ratio is used to determine signal strength for the AT42QT1011-TSHR. This signal-to-noise ratio is designed using an advanced mutual sampling technology. The signal-to-noise ratio is approximate to 4.9, which indicates that the signal is strong and precise. The mutual sampling technology also provides advanced noise canceling capabilities and wide dynamic range.
The AT42QT1011-TSHR offers several settings that allow the designer to adjust the sensitivity and power saving mode. The individual setting parameters can be modified to provide the desired functionality. The power saving mode allows the device to transition to lower power when idle and then quickly turn on when a touch sensor is triggered.
The AT42QT1011-TSHR capacitive touch sensor is an excellent choice for a range of interface detection applications. Its combination of high signal-to-noise ratio, high sensitivity and small package size makes it ideal for use in notebook PCs, tablets and other high-end applications. It provides reliable detection of finger press actions and superior noise canceling capabilities. By using a combination of settings, the designer can customize the device for their specific application.
