description: |
|
|
Provides both power and acts as the reference supply on the mcp4725.
|
|
For the mcp4726 it will be used as the reference voltage if vref-supply
|
|
is not provided.
|
|
|
|
vref-supply:
|
|
description:
|
|
Vref pin is used as a voltage reference when this supply is specified.
|
|
|
|
microchip,vref-buffered:
|
|
type: boolean
|
|
description: |
|
|
Enable buffering of the external Vref pin. This boolean is not valid
|
|
without the vref-supply. Quoting the datasheet: This is offered in
|
|
cases where the reference voltage does not have the current
|
|
capability not to drop its voltage when connected to the internal
|
|
resistor ladder circuit.
