  CDAC Architecture Gives ADC574 Pinout /Sampling, Low Power, New Input Ranges
  PDF, 54 Kb, Archivo publicado: sept 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.

  Complete Temp Data Acquisition System From a Single +5V Supply
  PDF, 68 Kb, Archivo publicado: 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.

  Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
  PDF, 227 Kb, Revisión: A, Archivo publicado: 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
