 1. Supported devices
 ====================
 
 * `ADE9000 <https://www.analog.com/media/en/technical-documentation/data-sheets/ADE9000.pdf>`_

-The ADE9000 is a highly accurate, fully integrated, multiphase energy and power
-quality monitoring device. Superior analog performance and a digital signal
-processing (DSP) core enable accurate energy monitoring over a wide dynamic
-range. An integrated high end reference ensures low drift over temperature
-with a combined drift of less than ±25 ppm/°C maximum for the entire channel
-including a programmable gain amplifier (PGA) and an analog-to-digital

+The ADE9078 does not provide the on-chip dip/swell (sag) detection available on

+available on the ADE9000.
