  Interfacing the ADS8401/ADS8411 to TMS320C6713 DSP
  PDF, 260 Kb, Archivo publicado: sept 23, 2004
  This application report presents a solution for interfacing the ADS8401 and ADS8411 16-bit, parallel interface converters to the TMS320C6713 DSP. The hardware solution consists of existing hardware, specifically the ADS8411EVM, 'C6713 DSK, and 5-6K interface board. The software demonstrates how to use an EDMA ping-pong buffer and Timer1 peripherals to collect data at 2 MSPS. Discussed also are som

  Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
  PDF, 227 Kb, Revisión: A, Archivo publicado: 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

  PDF, 215 Kb, Archivo publicado: marzo 17, 2011
  The input structure circuit of a successive-approximation register analog-to-digital converter (SAR ADC) incombination with the driving circuit forms a transfer function that can be used to determine minimum acquisition times for different types of applied input signals. This application report, which builds on Determining Minimum Acquisition Times for SAR ADCs When a Step Function is Applied to
