Application Notes
- Delta-Sigma ADC Design for Bridge Sensor ApplicationsPDF, 98 Kb, File published: Sep 30, 2011
This application report reviews several different types of bridge sensors, including characteristics of each type, and discusses the key parameters of delta-sigma (О”ОЈ) analog-to-digital converters (ADCs) at the system level. Additionally, the parameters of a О”ОЈ ADC are considered for use in common bridge sensor applications - 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.
