7 title: Microchip mcp4725 and mcp4726 DAC
10 - Tomas Novotny <tomas@novotny.cz>
23 Provides both power and acts as the reference supply on the mcp4725.
24 For the mcp4726 it will be used as the reference voltage if vref-supply
29 Vref pin is used as a voltage reference when this supply is specified.
31 microchip,vref-buffered:
34 Enable buffering of the external Vref pin. This boolean is not valid
35 without the vref-supply. Quoting the datasheet: This is offered in
36 cases where the reference voltage does not have the current
37 capability not to drop its voltage when connected to the internal
38 resistor ladder circuit.
