  • CDAC Architecture Gives ADC574 Pinout /Sampling, Low Power, New Input Ranges
    PDF, 54 Kb, 档案已发布: Sep 27, 2000
    This application note compares basic current-mode successive approximation A/Ds with CDAC-based architectures, and shows how adding a resistor divider network to the CDAC input permits the Burr-Brown ADS574 and ADS774 to fit existing ADC574 sockets. It then goes on to descibe some new analog input voltage ranges available on these parts due to the resistor network and CDAC approach.
  • A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)
    PDF, 425 Kb, 修订版: B, 档案已发布: Oct 9, 2011
    This glossary is a collection of the definitions of Texas Instruments' Delta-Sigma (О”ОЈ), successive approximation register (SAR), and pipeline analog-to-digital (A/D) converter specifications and performance characteristics. Although there is a considerable amount of detail in this document, the product data sheet for a particular product specification is the best and final reference.
  • Complete Temp Data Acquisition System From a Single +5V Supply
    PDF, 68 Kb, 档案已发布: Oct 2, 2000
    The CMOS ADS574 and ADS774 are drop-in replacements for industry standard ADC574 analog-to-digital converter, offering lower power and the capability to operate from a single +5V supply. The switched capacitor array architecture (CDAC), with the input resistor divider network to provide ADC574 input ranges, also allow the new parts to handle additional input ranges, including a 0V to 5V range. Thi
  • 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

    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
