This datasheet describes the ADE7912 and ADE7913, isolated 3-channel Sigma-Delta ADCs for three-phase energy metering using shunt sensors and iCoupler…
The ADE7912 and ADE7913 are isolated 3-channel Sigma-Delta analog-to-digital converters (ADCs) designed for three-phase energy metering using shunt sensors. Data and power isolation are achieved using Analog Devices' iCoupler technology. The ADE7912 integrates two 24-bit ADCs, while the ADE7913 integrates three ADCs. Both devices feature an integrated isoPower isolated DC-DC converter, making them suitable for applications such as power quality monitoring, solar inverters, and industrial PLCs.
