Application Notes
- Using Ceramic Resonators with the ADS1255/6PDF, 233 Кб, Файл опубликован: 9 июл 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 Кб, Версия: A, Файл опубликован: 29 янв 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.
