- **voltage** (**Required**, voltage): The output voltage range of the DAC. Must be one of ``5V`` or ``10V``.

Output
------

.. code-block:: yaml

    output:
      - platform: gp8403
        id: my_gp8403_output_1
        gp8403_id: my_gp8403
        channel: 0
      - platform: gp8403
        id: my_gp8403_output_2
        gp8403_id: my_gp8403
        channel: 1

Configuration variables:

- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- **gp8403_id** (*Optional*, :ref:`config-id`): The ID of the GP8403 component.
  Defaults to the only GP8403 component if there is only one.
