+    :description: Instructions for setting up MCP47A1 outputs on the ESP.
+    :image: mcp47a1.svg
+
+The ``mcp47a1`` output component allows to use `6bit external DAC <https://www.microchip.com/en-us/product/MCP47A1>`__
+in order to have analog output(s) on any board by using I²C. Devices default address is ``0x2E``
+and configurable alternative is ``0x3E``.
+
+.. code-block:: yaml
+
+    # Example configuration entry
+
+    # Set a global I²C connection
+    i2c:
+      sda: 21
+      scl: 22
+      scan: true
+
+    # Set the output with default (address: 0x2E / global I²C)
+    output:
+      - platform: mcp47a1
+        id: dac_output
+
+    on_...:
+      then:
+        - output.set_level:
+            id: dac_output
+            level: 100%
+
+
+Configuration variables:
+------------------------
+
+- **id** (**Required**, :ref:`config-id`): The id to use for this output component.
+- **address** (*Optional*, int): Manually specify the I²C address of
+  the DAC. Defaults to ``0x2E``.
+- All other options from :ref:`Output <config-output>`.
