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 - Inputs Currents for High-Resolution ADCsPDF, 127 Кб, Файл опубликован: 6 мар 2003
