  • A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)
    PDF, 425 Kb, 修订版: B, 档案已发布: Oct 9, 2011
    This glossary is a collection of the definitions of Texas Instruments' Delta-Sigma (О”ОЈ), successive approximation register (SAR), and pipeline analog-to-digital (A/D) converter specifications and performance characteristics. Although there is a considerable amount of detail in this document, the product data sheet for a particular product specification is the best and final reference.
  • Apply TI TSC for Various and Multiple Functions
    PDF, 316 Kb, 档案已发布: Dec 11, 2006
    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, 修订版: A, 档案已发布: 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
  • Interfacing the ADS7842 ADC to the TMS320C5400 and TMS320C6000 DSPs Platforms

    PDF, 215 Kb, 档案已发布: Mar 17, 2011
    The input structure circuit of a successive-approximation register analog-to-digital converter (SAR ADC) incombination with the driving circuit forms a transfer function that can be used to determine minimum acquisition times for different types of applied input signals. This application report, which builds on Determining Minimum Acquisition Times for SAR ADCs When a Step Function is Applied to
