  • Using the ADS7800 12 Bit ADC with Unipolar Input Signals
    PDF, 37 Kb, 档案已发布: Oct 2, 2000
    The ADS7800 12 bit Sampling analog-to-digital-converter is designed to operate with bipolar inputs of В±5V or В±10V. With the addition of an external amplifier, the ADS7800 can be used for 10V or 20V unipolar inputs. Four unipolar input options are shown in this Bulletin.
  • A Clarification of Use of High-Speed S/H to Improve Sampling ADC Performance
    PDF, 53 Kb, 档案已发布: Oct 2, 2000
    You know it's going to be one of those days when you see the printed version of an article you wrote and realize that you have made an error in the presentation of your ideas. This is what happened to me as I read Use High Speed S/H to Improve Sampling ADC Performance (Design Update, Vol.1, No.1). This article will rectify the situation and further illuminate some important performance aspe

  • 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
  • Determining Minimum Acquisition Times for SAR ADCs, part 2
    PDF, 215 Kb, 档案已发布: 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
