ADE7769 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 w

ADE7769 General 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. This approach provid.
