ADE7769 Datasheet (Analog Devices)

ADE7769, Energy Metering

of an IEC61036 (equivalent to IEC62053-21) low cost, watt-hour meter reference design.

The only analog circuitry used in the ADE7769 is in the Σ-Δ ADCs and reference circuit.

All other signal processing, such as multiplication and filtering, is carried out in the digital domain.
