  Upgrading From ADS7808/09 to ADS8508/09 Devices
  PDF, 66 Кб, Файл опубликован: 12 июн 2007
  The information contained in this document applies to current applications using the ADS7808 or ADS7809 in a surface-mount SOIC (DW) package.This document is a guide to users of the ADS7808/09 devices with regards to potential compatibility issues when upgrading to the new ADS8508 and ADS8509 series of devices.

  ADS7809 Tag Features
  PDF, 50 Кб, Файл опубликован: 27 сен 2000
  The ADS7809 is part of a family of capacitive redistribution SAR A/D converters that feature a serial output and a tag pin for cascading multiple converters. Other members of this family include the ADS7806, ADS7807, ADS7808, ADS7824, and ADS7825. Note that the even numbered converters are 12-bit converters and the odd numbered converters are 16-bit converters.

  Tips for Using the ADS78xx Family of A/D Converters
  PDF, 24 Кб, Файл опубликован: 27 сен 2000
  The input to each of the members of the ADS Family (ADS7804/05/06/07/08/09/10/19, so far) is a resistor divider network, converting the input signal to the range used internally. This resistor divider offers inherent overvoltage protection, which will often simplify analog circuitry.

  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 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.
