Overview

A DAC or digital-to-analog converter converts digital input to analog output. This DAC uses a repeating cascade of resistors R and 2R. The main advantage is that only two type of resistors are required for any number of bits. The total resistance seen from any point will be corresponding to the binary position of that bit.
