Application Notes
- How to Use TI's 4-Wire TSC to Control an 8-Wire Resistive Touch ScreenPDF, 271 Кб, Файл опубликован: 27 мар 2006
This application report implements a Texas Instruments 4-wire touch screen controller (TSC) to control an 8-wire touch screen and discusses features and performances for such applications.Texas Instruments (TI) provides various TSC devices for the 4-wire or 5-wire touch screens (TS). A TI 4-wire TSC device, such as the ADS7843, TSC2003, or TSC2046, is ideal for controlling a 4-wire TS, but it - ADS7843 Pen InterruptPDF, 48 Кб, Файл опубликован: 27 сен 2000
The ADS7843 is a 12-bit sampling analog-to-digital converter (ADC) used to drive 4-wire touch-screens to serial interfaces by ratiometrically converting two differential input signals. The ADS7843 also produces an accurate output with the first conversion cycle once powered up. - Using a touch-screen controller’s auxiliary inputsPDF, 149 Кб, Файл опубликован: 12 окт 2007

- 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 - 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 - Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev.
