The AT42QT2160-MMUR is a high-precision capacitive touch sensing solution based on the AT42QT2160 chip. It is a four-channel layer of matrix type touchpad and is designed for use in a variety of applications. This article will discuss the application field and working principle of the AT42QT2160-MMUR.
The AT42QT2160-MMUR is specifically designed for use in industrial and commercial applications such as remote-control interface, handheld gaming devices and embedded interactive designs. It is especially suitable for applications that require accurate operation and is extremely durable. With its embedded self-calibration and power-on reset features, the AT42QT2160-MMUR provides highly reliable and consistent performance. Furthermore, the chip is completely immune to electrostatic discharge. As a result, the AT42QT2160-MMUR is suitable for use in environments with high levels of ESD.
The AT42QT2160-MMUR works on the principle of capacitive sensing. It consists of a matrix of sensors that are connected to a signal conditioning IC. The matrix is arranged in a 4-by-4 formation, with each touchpad input providing a resolution of up to 4.3 mm. The IC monitors the variation of capacitance across the surface of the touchpad, and when contact is made, the capacitance changes. The signal conditioning IC then processes the signal to make it suitable for further processing by the host electronics.
The AT42QT2160-MMUR is designed in such a way that it can detect finger touch, hover and pressure from objects, such as styluses. Moreover, it is capable of detecting up to 4 simultaneous touches. Furthermore, it offers a high degree of noise immunity, making it suitable for operating in noisy environments. Additionally, the AT42QT2160-MMUR features low power consumption and can detect objects even when the power is off. It also features a temperature stability of up to 170 degrees Celsius.
In conclusion, the AT42QT2160-MMUR is an ideal solution for a wide variety of industrial and commercial applications. It offers high precision, reliable performance and immunity from electrostatic discharge. It is capable of detecting touches, hovers and pressure from objects and with its low power consumption and high temperature stability, it is suitable for a variety of applications. Furthermore, its 4-by-4 matrix type touchpad provides a resolution of up to 4.3 mm, making it suitable for use in embedded interactive designs.
