Notas de aplicación
- Obtaining 17 Bits of Resolution using a 12-Bit A/D System on a ChipPDF, 337 Kb, Archivo publicado: jun 24, 2010
Integrated data acquisition systems can provide many benefits over discrete component designs. Superior performance, power, and cost savings, along with shorter development times, are among these benefits. Features such as integrated programmable gain amplifiers and averaging can provide added resolution. This application note includes information on how to achieve 17 bits of effective resolution - Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)PDF, 227 Kb, Revisión: A, Archivo publicado: nov 10, 2010
This application report analyzes a simple method for calculating minimum acquisition times for successive-approximation register analog-to-digital converters (SAR ADCs). The input structure of the ADC is examined along with the driving circuit. The voltage on the sampling capacitor is then determined for the case when a step function is applied to the input of the driving circuit. Three different - Determining Minimum Acquisition Times for SAR ADCs, part 2PDF, 215 Kb, Archivo publicado: marzo 17, 2011
The input structure circuit of a successive-approximation register analog-to-digital converter (SAR ADC) incombination with the driving circuit forms a transfer function that can be used to determine minimum acquisition times for different types of applied input signals. This application report, which builds on Determining Minimum Acquisition Times for SAR ADCs When a Step Function is Applied to - Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev.

- A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)PDF, 425 Kb, Revisión: B, Archivo publicado: 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.
