- Interfacing the ADS8371 to TMS320C6713 DSPPDF, 316 Kb, Archivo publicado: enero 4, 2005
This application report presents a solution to interfacing the ADS8371 16-bit, 750-KSPS, parallel interface converter to the TMS320C6713 digital signal processor of the TMS320? DSP family. The hardware solution is made up of existing hardware, specifically the ADS8371EVM, C6713 DSK, and 5-6K Interface Board. The software demonstrates how to use an EDMA ping-pong buffer and Timer1 peripherals to co - 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 - Determining Minimum Acquisition Times for SAR ADCs, part 2PDF, 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
