  Interfacing the ADS7881 to TMS320C6713 DSP
  PDF, 1.1 Mb, Archivo publicado: jun 30, 2005
  This application report presents a solution to interfacing the ADS7881 12-bit parallel interface converter to the TMS320C6713 DSP. The hardware solution is made up of existing hardware, specifically, the ADS7881EVM, 'C6713 DSK, and the 5-6K Interface Board. The software demonstrates how to use an EDMA ping-pong buffer and Timer1 peripherals to collect data at 4 MSPS. Discussed also are some of the

  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
