13description: |
14  The ADE9000 is a highly accurate, fully integrated, multiphase energy and power
15  quality monitoring device. Superior analog performance and a digital signal
16  processing (DSP) core enable accurate energy monitoring over a wide dynamic
17  range. An integrated high end reference ensures low drift over temperature
18  with a combined drift of less than ±25 ppm/°C maximum for the entire channel
19  including a programmable gain amplifier (PGA) and an analog-to-digital
20  converter (ADC).
