+The Microchip Technology Inc. MCP3008
+devices are successive approximation 10-bit Analogto-Digital (A/D) converters with on-board sample and
+hold circuitry. Each pin will respond with a 0-1023 result depending on the voltage it is reading

+MCP3008
+-------
+
+The MCP3008 component allows you to use MCP3008 8-Channel 10-Bit A/D Converter
+(`datasheet <http://ww1.microchip.com/downloads/en/DeviceDoc/21295d.pdf>`__,
+`Adafruit <https://www.adafruit.com/product/856>`__) in ESPHome.
+It uses the :ref:`SPI Bus <spi>` for communication.
+
+Once configured, you can use any of the 8 pins as
+sensors for your projects.
