signal by using a fast switching frequency, the hardware DAC can output a *real* analog signal with
no need for additional filtering.
The DAC spans across two pins, each on its own channel: GPIO25 (Channel 1) and GPIO26 (Channel 2).
The DAC spans across two pins, each on its own channel:
- ESP32: GPIO25 (Channel 0) and GPIO26 (Channel 1).
- ESP32 S2: GPIO17 (Channel 0) and GPIO18 (Channel 1).
The output level is a percentage of the board supply voltage (VDD_A) - generally this will be 3.3 V.

Configuration variables:
------------------------
- **pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin to use DAC on. Only GPIO25
and GPIO26 are supported.
- **pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The pin to use DAC on. See above for valid pin numbers.
- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
- All other options from :ref:`Output <config-output>`.
