| title: DAC emulation using a digital potentiometer |
| - Peter Rosin <peda@axentia.se> |
| It is assumed that the dpot is used as a voltage divider between the |
| current dpot wiper setting and the maximum resistance of the dpot. The |
| divided voltage is provided by a vref regulator. |
| | '---' dac output voltage |
| description: Regulator supplying the voltage divider. |
| Channel node of the dpot to be used for the voltage division. |
