title: Analog Devices ADE9000 High Performance, Polyphase Energy Metering

maintainers:

description: |
  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
  converter (ADC).
