Voltage Reference Wizard (downloadable)
This Wizard helps you select the most suitable voltage for a use with a data converter. Supply the Wizard with a given data converter; it will provide you with a number of suitable references plus the maximum DC error contributed to your overall system. Or enter the amount of DC error your system can tolerate and find out which of ADI’s reference and data converter pairs will meet your requirement.
