Notas de aplicación
- Using Ceramic Resonators with the ADS1255/6PDF, 233 Kb, Archivo publicado: 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, Revisión: A, Archivo publicado: enero 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. - Measuring Single-Ended 0V-5V Signals with Differential Delta-Sigma ADCs (Rev.

- Interfacing the ADS1251/52 to the MSP430PDF, 264 Kb, Archivo publicado: marzo 8, 2005
This application report demonstrates an effective method to interface the ADS1251 and ADS1252 sigma-delta data converters to the MSP430F449 microcontroller. The software for this application report was developed on the HPA449 development system. - 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.
