Improved Voltage Reference Circuits Maximize Converter Performance
Overview:
The performance of ADCs and DACs is tied directly to the performance of the associated voltage reference. Converters present a unique current demand load for the reference buffer amplifier. Understanding the load dynamics is necessary to insure the proper drive is supplied. Reference accuracy is a major factor in the overall accuracy of the conversion. Noise reduction techniques usually demand large filter capacitors. Various circuit topologies allow the voltage reference output to be stable with no degrading of the output voltage accuracy.
