  Interfacing the ADS8345 to TMS320C5416 DSP
  PDF, 1.5 Mb, 档案已发布: Dec 5, 2002
  This application report presents a hardware and software solution to interfacing the ADS8345 16-bit, 8-channel, 100 kHz analog-to-digital converter to the C5000? fixed point 16-bit family of digital signal processors (DSP). While this application report primarily focuses on the 8-channel ADS8345 part, the same solution can be utilized for the 4-channel ADS7841/ADS8341/ADS8343 and 8-channel ADS834

  Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
  PDF, 227 Kb, 修订版: A, 档案已发布: 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
