Data Acquisition - Touch Screen Controllers

The MAX11800GTC/V+ is a series of low power, industrial grade capacitive touch screen controllers designed to fit a variety of touchscreen applications. This touch screen controller family is engineered to help customers reduce power and increase functionality while enabling robust touch screen performance.

Application Field

The MAX11800GTC/V+ has a wide application field. It can be used to design and develop a new range of touchscreens and control surfaces for consumer, industrial and medical products. It can control capacitive touch screens for tablets, notebooks, monitors, handsets, whitegoods and appliances such as washing machines, ovens and medical equipment.

The MAX11800GTC/V+ is suitable for a wide range of striking design options, such as flat edges, round edges and curved edges for displays. This component also can be used in developing gaming products, portable medical devices and products requiring an IPX7 rating.

Working Principle

The MAX11800GTC/V+ is based on capacitive technology, which detects touch and draws power from the display or other electronic component connected to it. It is equipped with a power-saving, two-electrode detection technique that helps eliminate the need for a static ground or guard trace. Its low power operation and small form factor with 0.8 mm QFN package make it ideal for space-constrained designs.

The MAX11800GTC/V+ controller features a “filter” parameter which can accurately report touch on the screen and prevent false readings from external sources, such as power lines, radio transmitters, EMI, and any other potential interference. In addition, the Controller boasts an “update rate” parameter that allows for the selection of a touch refresh time for improved latency and the prevention of ghosting. By combining user configurable touch logic thresholds and the onboard noise filter, the MAX11800GTC/V+ allows for a smooth, reliable and consistent user experience.

The controller can also be configured for multi-touch operations which are ideal for gaming, gesturing and navigation in consumer applications. By enabling these capabilities, designers are able to unlock new user experiences and provide an intuitive touchscreen interaction.

Conclusion

The MAX11800GTC/V+ is an ideal touch screen controller for a wide range of consumer, industrial and medical applications. With its low power operation, small form factor and range of features and capabilities, it is an impressive and reliable solution for any design.
