Working Principle

At the heart of the MAX11803ETC+T is a highly efficient capacitance-to-digital converter (CDC) IC designed to convert capacitive signals into digital information. The IC operates on the principle of mutual capacitance, where changes in capacitance are detected between the human body and the touch screen electrodes. The IC measures the mutual capacitance between the electrodes and then converts it into digital signals. For increased accuracy, the CDC IC uses a capacitance divider circuit to reduce the measurement range.

The MAX11803ETC+T is designed to provide superior accuracy and robust performance. It utilizes a combination of advanced proprietary technologies, such as Noise Prediction Filtering (NPF) and advanced Signal-to-Noise Ratio (SNR) optimization, to maximize the sensitivity and accuracy of the touch screen controller. The controller is also flexible, allowing users to set up their own custom performance and response settings.

The MAX11803ETC+T also offers a number of key features, including an integrated temperature sensor and support for multiple I/O data formats. The controller is designed to meet the needs of next-generation touch screen applications, providing accuracy, flexibility, and robust operation.

The MAX11803ETC+T touch screen controller is an excellent product for a variety of data acquisition and touch screen applications. Its robust CDC technology and advanced capabilities make it a reliable and powerful solution for a wide range of markets.
