ADE9078ACPZ

ADE9078 is a highly accurate, fully integrated energy metering device. Interfacing with both current transformer (CT) and Rogowski coil sensors, it enables users to develop a 3-phase metrology platform, which achieves high performance for class 1 upto class 0.2 meters. It integrates seven high performances ADCs and a flexible DSP core. An integrated high end reference ensures low drift over temperature with a combined drift of less than ±25ppm/°C maximum per channel, each of which includes a programmable gain amplifier (PGA) and ADC. It offers an integrated flexible waveform buffer that stores samples at a fixed data rate or a sampling rate that varies based on line frequency to ensure 64 points per line cycle. These two options make it easy to implement harmonic analysis in an external processor according to IEC 61000-4-7. It is used in applications such as polyphase meters, power quality monitoring, protective device.

• 7 high performance analog-to-digital converters (ADCs)
