  Calibration Routines and Register Value Generation for the ADS121x Series
  PDF, 298 Kb, 档案已发布: Jun 19, 2003
  In order to achieve the best possible performance, offset and gain can be often be calibrated in high-resolution analog-to-digital converters (ADCs). Changes in temperature, PGA gain, power supply voltage, or most importantly, decimation ratio can influence the accuracy of measurement. This application note explains how the calibration routines work and how to generate values for the full-scale re
