  • Interfacing the MSOP8EVM to TMS470 Processors
    PDF, 68 Kb, Datei veröffentlicht: Mar 15, 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 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
  • Determining Minimum Acquisition Times for SAR ADCs, part 2
    PDF, 215 Kb, Datei veröffentlicht: 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

  • A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)
    PDF, 425 Kb, Revision: B, Datei veröffentlicht: 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.
  • Interleaving Analog-to-Digital Converters
    PDF, 64 Kb, Datei veröffentlicht: Oct 2, 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 Kb, Datei veröffentlicht: Oct 2, 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.
