Only a few know the differences in architecture and what advantages and disadvantages a string architecture has over an R2R ladder, and vice versa. Knowing the differences and how those general purpose DACs work enables the designer to choose the best DAC for their application. This article will shed some light on the basic operation of DACs and will give some answers to questions you always wanted to know.
