  Using the ADS7841 and ADS7844 with 15-Clock Cycles
  PDF, 188 Кб, Файл опубликован: 30 июн 2005
  This application report presents an analysis on the use of the 15-clock cycle method of operation for the ADS7841 and ADS7844 described in their respective data sheets. The advent of commercially available processors such as the TMS470 no longer restricts users from implementing the 15-clock method with simple microprocessors. This method, however, does present some challenges to the software inte

  Apply TI TSC for Various and Multiple Functions
  PDF, 316 Кб, Файл опубликован: 11 дек 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 Кб, Версия: A, Файл опубликован: 10 ноя 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

  PDF, 425 Кб, Версия: B, Файл опубликован: 9 окт 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.

  Interleaving Analog-to-Digital Converters
  PDF, 64 Кб, Файл опубликован: 2 окт 2000
  It is tempting when pushing the limits of analog-to-digital conversion to consider interleaving two or more converters to increase the sample rate. However, such designs must take into consideration several possible sources of error.

  What Designers Should Know About Data Converter Drift
  PDF, 95 Кб, Файл опубликован: 2 окт 2000
  Exactly how inaccurate will a change in temperature make an analog-to-digital or digital-to-analog converter? As designers are well aware, a 12-bit device may provide a much lower accuracy at its operating-temperature extremes, perhaps only to 9 or even 8 bits. But for lack of more precise knowledge, many play it safe (and expensive) and overspecify.
