    This report presents a method for comparing the ac performance of the TLV2462 and TLV2772 operational amplifiers to the ac performance of the TLV2544/TLV2548 analog-to-digital converter.
  • 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
