This datasheet details the Analog Devices ADE7978 and ADE7933/ADE7932 chipsets for three-phase energy metering using shunt current sensors.
The ADE7978 and ADE7933/ADE7932 form a dedicated chipset that uses shunts as current sensors for three-phase energy metering. The ADE7933 and ADE7932 are isolated 3-channel Σ-Δ ADCs suitable for applications using shunt current sensors, featuring integrated isoPower® isolated DC-DC converters based on iCoupler technology.
