- Synchronizing the ADS1271PDF, 82 Kb, Datei veröffentlicht: Oct 27, 2005
Synchronization on the ADS1271 serves two purposes. Most often, it is used to enable simultaneous sampling by multiple ADS1271s, typically through a daisy-chainconfiguration. Synchronization can also be used to match the conversion cycle of the ADS1271 to external events. In the first section of this application note, we show howto synchronize multiple ADS1271s to each other.

- A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)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. - Principles of Data Acquisition and Conversion (Rev.
