ADE7768 - Energy Metering

Datasheet Summary

Description

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.

Features

  • On-chip oscillator as clock source High accuracy, supports 50 Hz/60 Hz IEC62053-21 Less than 0.1% error over a dynamic range of 500 to 1 Supplies positive-only average real power on frequency outputs F1 and F2 High frequency output CF calibrates and supplies instantaneous, positive-only real power Logic output REVP indicates potential miswiring or negative power Direct drive for electromechanical counters and 2-phase stepper motors (F1 and F2) Proprietary ADCs and DSPs provide high accuracy over.
