Step 1: Voltage Ranges and Reference-Voltage Determination

The first consideration when selecting a voltage reference for a DAC application is to evaluate the supply-voltage and the DAC output-voltage ranges (Table 2). To simplify the design examples described above, DACs have already been chosen, so their output gain is not a variable we will trade off as in a real design.

Main Design Objectives
Low cost, loose accuracy
High absolute accuracy and precision
One-time calibrated, low drift
Low voltage, battery powered, moderate accuracy
Example Application
