Application Notes

• Download
  Using Ceramic Resonators with the ADS1255/6
  PDF, 233 Kb, File published: 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

  Seismic Sensor Demonstration Using an ADS1255 and TMS320VC5510A DSP (Rev. A)
  PDF, 193 Kb, Revision: A, File published: Jan 29, 2009
  A prototype system for seismic sensing for such applications as oil exploration, earthquake detection, and acoustic monitoring is described. The system uses a delta-sigma converter and low-power DSP. Measured system performance met the requirements for such systems.

  PDF, 425 Kb, Revision: B, File published: 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.
