ADE7768 Datasheet Energy Metering

Manufacturer: Analog Devices

Datasheet Details

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

The only analog circuitry used in the ADE7768 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.
