    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
  • Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
    PDF, 227 Kb, Revision: A, Datei veröffentlicht: Nov 10, 2010
    This application report analyzes a simple method for calculating minimum acquisition times for successive-approximation register analog-to-digital converters (SAR ADCs). The input structure of the ADC is examined along with the driving circuit. The voltage on the sampling capacitor is then determined for the case when a step function is applied to the input of the driving circuit. Three different
