  Interfacing the MSOP8EVM to TMS470 Processors
  PDF, 68 Кб, Файл опубликован: 15 мар 2006
  This application report presents a method for interfacing the modular MSOP8EVM, an evaluation module (EVM) for single-channel, low-power, 8- to 16-bit serial analog-to-digital converters to the TMS470 series microcontrollers. The hardware used for this example includes the TMS470 Kickstart Development Kit evaluation kit featuring the 60-MHz TMS470R1B1M and the HPA-MCU Interface Board. The soft

  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.
