Build a simple 1-wire digital/analog converter (DAC)

Among devices available with a 1-wire interface, the best known are memories, temperature sensors, battery monitors, and addressable switches.

This article, by Bernhard Linke of Maxim, shows how to do this, and it includes full analysis as well as the circuit schematic.
