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).
