- Interfacing the ADS8401/ADS8411 to TMS320C6713 DSPPDF, 260 Кб, Файл опубликован: 23 сен 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.

This application report presents a solution for interfacing the ADS8402 and ADS8412 16-bit, parallel interface converters to the TMS320C6713 DSP. The hardware solution consists of existing and orderable hardware, specifically the ADS8402EVM, 'C6713 DSK, and 5-6K interface board. The software demonstrates how to use the EDMA controller to efficiently collect data from the data converter. Discussed - Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)PDF, 227 Кб, Версия: A, Файл опубликован: 10 ноя 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 2PDF, 215 Кб, Файл опубликован: 17 мар 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.
