This design idea revisits another: “PWM power DAC incorporates an LM317.” Like the earlier circuit, this one implements a power DAC by integrating an LM317 positive regulator into a mostly passive PWM ...

Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 A current source. It profits from the accurate internal voltage reference ...

Grenoble, France -- October 31, 2013-- Dolphin Integration rolls out sDACa-MT1.01, an ultra dense Pulse Width Modulated DAC for audio applications embedding valuable features for easier SoC ...

PWM was one choice, and some example code uses ... Of course, this won’t apply to every project where you need a DAC, but it still might give you some ideas. We have looked at PDM before.
