  • 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
  • Interfacing the ADS786x to the MSP430F2013
    PDF, 90 Kb, 档案已发布: Jun 15, 2006
    This application report presents methods of interfacing the ADS7866/67/68 12/10/8-bit SAR analog-to-digital converter to the MSP430F2013 universal serial interface (USI) in SPI mode. The flexible clocking scheme of the USI port, along with the internal 16-bit shift register, provides an easy hardware/software interface to this series of high-speed, micro-power SAR converters.

    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
  • 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.
