Interfacing the ADS786x to TMS470 Processors
PDF, 59 Kb, 档案已发布: Jul 10, 2006
This application report presents methods of interfacing the ADS7866/67/68 12/10/8-bit SAR analog-to-digital converter to the serial peripheral interface (SPI) port of the TMS470 processors. The flexible clocking scheme of the TMS470 SPI port, along with its internal 16-bit shift register provides an easy hardware/software interface to this series of high-speed, micro power SAR converters.

Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
PDF, 227 Kb, 修订版: A, 档案已发布: 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
