  ADS7809 Tag Features
  PDF, 50 Kb, Datei veröffentlicht: Sep 27, 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.

  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.

  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.

  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.

  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.
