The ADS7843, ADS7845, and the new ADS7846 converters all are designed for specific touch screen applications. Applications using these devices can benefit greatly from the tips presented in this application bulletin. Most of the examples discuss the ADS7843, but the techniques shown are applicable to all of the devices. - Calibration in touch-screen systemsPDF, 169 Кб, Файл опубликован: 10 авг 2007

This application report presents several examples showing how a touch screen controller (TSC) from Texas Instruments provides a variety of functions such as graphs, scroll bars, pressure buttons, and analog dials. A simple resistive TSC can be used to achieve all of these functions as long as they are not activated simultaneously. This application report demonstrates a few simple examples how th - Reducing Analog Input Noise in Touch Screen Systems (Rev. A)PDF, 535 Кб, Версия: A, Файл опубликован: 15 сен 2007
This application report discusses some common methods for reducing noise in the analog input circuitry of a resistive touch screen controller. In terms of hardware design, PCB layout and grounding are critical; the additional noise-decoupling capacitor built into a touch screen controller input pin may also help. On the software side, several simple, widely-applied filtering algorithms are present - PCB Layout Guideline for TI Resistive TSC DevicesPDF, 144 Кб, Файл опубликован: 4 окт 2012
