Calculating the Error Budget in Precision Digital-to-Analog Converter (DAC) Applications

By: David Fry

Abstract: This application note analyses the parameters that affect the errors in precision digital-to-analog converter (DAC) applications. The analysis focuses on the factors introduced by both the data converter and the voltage reference. It describes the calculations required to select the data converter and the reference to meet the system's target specifications. The calculations are available in a spreadsheet.
