Application Notes
- Using Ceramic Resonators with the ADS1255/6PDF, 233 Kb, File published: 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, Revision: A, File published: Jan 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, File published: Mar 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. - Digital Filter Types in Delta-Sigma ADCsPDF, 219 Kb, File published: Jun 27, 2017
This application report discusses digital filters which are a ubiquitous feature in delta-sigma analog todigital converters (ADCs). Digital low-pass filters are essential to the functionality of a delta-sigma ADCwhich relies on oversampling and noise shaping to push quantization noise out of band. There arevariations between the types of digital filters used in delta-sigma ADCs that provide - Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev.
