Application Notes

- A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)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 ConvertersPDF, 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. - Apply TI TSC for Various and Multiple FunctionsPDF, 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 - What Designers Should Know About Data Converter DriftPDF, 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. - Principles of Data Acquisition and Conversion (Rev. A)PDF, 132 Кб, Версия: A, Файл опубликован: 16 апр 2015
- Determining Minimum Acquisition Times for SAR ADCs, part 2PDF, 215 Кб, Файл опубликован: 17 мар 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 - Using the ADS7841 and ADS7844 with 15-Clock CyclesPDF, 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
