  • Interfacing the ADS7881 to TMS320C6713 DSP
    PDF, 1.1 Mb, Datei veröffentlicht: 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, Revision: A, Datei veröffentlicht: 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
  • Determining Minimum Acquisition Times for SAR ADCs, part 2
    PDF, 215 Kb, Datei veröffentlicht: Mar 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
