ADE7769 - Energy Metering

Description

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.

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 average real power on frequency outputs F1 and F2 High frequency output CF calibrates and supplies instantaneous real power CF output remains logic high when ADE7769 is under no-load threshold Logic output REVP indicates a potential miswiring or negative power Direct drive for electromechanical counters and 2-phase stepper motors (F1 and F2) Proprietar.
