Notas de aplicación

  • Using Ceramic Resonators with the ADS1255/6
    PDF, 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.

  • Interfacing the ADS1251/52 to the MSP430
    PDF, 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.
  • Digital Filter Types in Delta-Sigma ADCs
    PDF, 219 Kb, Archivo publicado: 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
