应用须知

  • Interfacing the ADS1251/52 to the MSP430
    PDF, 264 Kb, 档案已发布: Mar 8, 2005
    This application report demonstrates an effective method to interface the ADS1251 and ADS1252 sigma-delta data converters to the MSP430F449 microcontroller. The software for this application report was developed on the HPA449 development system.
  • A Spreadsheet for Calculating the Frequency Response of the ADS1250-54 (Rev. A)
    PDF, 461 Kb, 修订版: A, 档案已发布: Sep 5, 2003
    The ADS1250, ADS1251, ADS1252, ADS1253 and ADS1254 family of high-resolution analog-to-digital converters (ADCs) share an advanced delta-sigma (О”ОЈ) topology. This application note reviews the frequency characteristics of these devices and shows how to use a companion Microsoft Excel? spreadsheet (sbaa103a.zip), available for download from the TI web site, to calculate the frequency res
  • AB-174: Getting the Full Potential from your ADC (Rev. A)
    PDF, 72 Kb, 修订版: A, 档案已发布: Jun 28, 2002
    Many of today?s high-resolution ADCs (Analog-to-Digital Converters) are operating from a single supply and use fully differential inputs. This can be a problem for single-ended signals that are bipolar relative to common. This article illustrates circuit configurations that preserve the full-scale input range by using modern features, such as Programmable Gain Amplifiers (PGAs) and internal voltag
  • Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev. A)

  • 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.
