  • How delta-sigma ADCs work, Part 1 (Rev. A)
    PDF, 666 Kb, Revision: A, Datei veröffentlicht: Sep 19, 2016
    Analog techniques have dominated signal processing for years, but digital techniques are slowly encroaching into this domain. The design of delta-sigma (О”ОЈ) analog-to-digital converters (ADCs) is approximately three-quarters digital and one-quarter analog. О”ОЈ ADCs are now ideal for converting analog signals over a wide range of frequencies, from DC to several megahertz. Basically, these conv
  • Using Ceramic Resonators with the ADS1255/6
    PDF, 233 Kb, Datei veröffentlicht: Jul 9, 2004
    The ADS1255 and ADS1256 each have an onboard clock generator designed to use an external crystal to create the system clock. External ceramic resonators can also be used, since resonators operate with a similar clock generator circuit. Compared with quartz crystals, resonators typically are less accurate and have lower Q, and must be carefully evaluated before being used with either the ADS1255/6

    PDF, 219 Kb, Datei veröffentlicht: Jun 27, 2017
    This application report discusses digital filters which are a ubiquitous feature in delta-sigma analog todigital converters (ADCs). Digital low-pass filters are essential to the functionality of a delta-sigma ADCwhich relies on oversampling and noise shaping to push quantization noise out of band. There arevariations between the types of digital filters used in delta-sigma ADCs that provide

    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.
