  Using the ADS7800 12 Bit ADC with Unipolar Input Signals
  PDF, 37 Kb, File published: 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.

  Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
  PDF, 227 Kb, Revision: A, File published: 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

  Interleaving Analog-to-Digital Converters
  PDF, 64 Kb, File published: Oct 2, 2000
  It is tempting when pushing the limits of analog-to-digital conversion to consider interleaving two or more converters to increase the sample rate. However, such designs must take into consideration several possible sources of error.

  What Designers Should Know About Data Converter Drift
  PDF, 95 Kb, File published: Oct 2, 2000
  Exactly how inaccurate will a change in temperature make an analog-to-digital or digital-to-analog converter? As designers are well aware, a 12-bit device may provide a much lower accuracy at its operating-temperature extremes, perhaps only to 9 or even 8 bits. But for lack of more precise knowledge, many play it safe (and expensive) and overspecify.
