A)PDF, 191 Kb, Revision: A, File published: Apr 13, 2010
This document discusses the characteristics of electrocardiogram (ECG) signals and different front-endapproaches for ECG signal acquisition. The tradeoffs between different approaches and the effects on overall system design are discussed. The report also includes descriptions of potential implementations of the front-end architecture using the ADS1258 and ADS1278 and respective noise measuremen - Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev. A)PDF, 69 Kb, Revision: A, File published: May 18, 2015
- A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)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. - Principles of Data Acquisition and Conversion (Rev.
